I think they are referring to 700 footprint aftermarket action with CRF
Aftermarket 700 actions that are CRF

I originally posted because I wanted to look into what was available but this thread has already shared some helpful information so for all intended purposes this is going to be strictly a target rifle.
You are correct and Dennis has already addressed this but your post got me wondering and hoping someone might be able to answer this.
Do some aftermarket 700 footprints have different actions? For example a 700 footprint but a Mauser action therefore being controlled feed without jeopardizing the original design or have they reworked the original 700 design?
They need to make the extractor pop over the rim on the new crf actions because they don't feed right in the first place. I found half the time with my cz 550 the cartridge would be in front of the extractor when the magazine released it, and it would proceed into the chamber push feed style. However it would still feed upside down just like all my pushfeeds I have tried. Also I wonder about the superior strength of the crf extractor when it is free to pop back over the rim I assume the Mauser 98 had the non popover extractor so the rim would have to move back with the extractor even if the cartridge is hard to pull out. my winchester crf did feed properly though
I have a Defiance Deviant SA with Mauser style claw extractor. Why? I just like CRF for hunting and I wanted a SA with CRF. Why not sure. I don't even like SA, LOL. The only benefit I really see is if you happen to not close the bolt fully on PF and the round stays in the chamber or partially in. Then you try to feed another one in. Jam. Short-stroking the action is also less of a problem on a CRF. Then again short stroking a PF will probably eject the empty anyway before you load another one or you will not be able to close on an empty case, realizing the problem. So, I do not see that as an issue unless you are trying to eject a round that failed to fire and has the bullet still in it and you short stroke, not ejecting it, yet grab another one from the mag/follower. The PF may jam. You can also jam a CRF depending on how hard or slow you work the action, etc., so I say get what you want and don't worry much. As long as you get used to how they work, you will be fine. Though I'd think even old 20th century (1908 model and up) Mausers and CZs are as strong as Rem 700, I do not have any data to support one over the other. Anything can fail.
I further believe the Mausers had extractors that snapped over the rim of the case. Can't imagine soldiers using Mauser not being able to single feed in a pinch. But anything is possible. The only rifles that did not pop over the rim was my buddy's Ruger Gun Scout rifle in .308. Mine did. His just did not have enough relief in the cut and the extractor was slightly bigger than mine in the claw shape and thickness. That added up. Then a Mauser or a Brno 21 I think but regardless of which, that one had few non original parts, so who knows where the extractor came from. Put a different bolt in it as a test and it snapped over.
CRF on a Mauser was nice as the C-ring in the receiver was used as torque shoulder against which the barrel was tightened and you could swap barrels easily. Also, less machining on the barrel. Just threads and flat surface at breech end. No cones, no relief cuts, etc. With systems like Defiance, Winchester, Kimber, etc. you have to always turn the barrel to the same spot exactly as it has a relief cut for the extractor as they tighten against the front of the receiver.
PFs are also generally slicker than CRFs, especially when tight tolerances are used. When trying not to disturb the rifle in a rest, that might matter.

Strongest ... maybe 1 design that is, safest Meh ... I dont think so ... the Bolt can be opened on Safe - doesn't lock. To me that's ####ty, that's why I had bought a couple and dumped them ... thats why I don't use them, that just doesn't interest me. You do you ✔
Does you Deviant CRF feed from the chamber? My Rebel did not. It's with the gunsmith getting that remedied.
What is particularily safe about a loaded chamber that in order to unload it requires you disengage the safety?
To someone familiar with the firearm it's not a big deal... but to the majority of goof balls out there it is a big deal...
I think there is a fair bit of folks unfamiliar with firearms operations that passed courses, hunt, own firearms etc.
I can't tell you how many people I've run into with blind mags that think you have to fully cycle the action to unload the mag, ie chamber round and close bolt, extract and eject on the ground...
When I show them how to do it properly and safely, and how gravity works, and they don't need to dump loaded cartridges in the dirt and just roll it over into your hand, it's like they just found religion or something, the lightbulb fire's up and they get it lol.
I think the guy you quoted is referring to 3 position safeties, or along those lines, where the safety can lock the bolt closed, preventing thick brush hiking from inadvertently opening the bolt opening the action, dumping your round, whatever. I've never had it happen personally, but I guess it a possibility. Don't see how it could ruin my hunt, and this isn't even the hunting thread, supposed to be talking target guns, which many don't even have a safety, only time they get a round loaded is when the rifle is benched pointing down range.
