Two point slings are quite useful for front carry as well, especially if you build a shorty. Traditionalists who like that balance point under the action to ride nicely in their hand will need to adapt to an entirely different platform as I suggested. But military and law enforcement carry at the ready all the time with essentially chassis style ergos and they use two point slings, you can snug them fast for when you need to bend or get through or over a fence and they loosen super quick for fast shouldering. Once you actually try some of this out it's pretty eye opening stuff that transitions well to hunting. But yes the discussion can definitely go to two different types of chassis builds. Most are building prs style heavy target rigs that would not translate to hunting at all, too long, too heavy. HOWEVER, if you look at this more like the AR guys build up AR's you can build more along those lines, shorter/lighter rigs that handle very fast off a two point sling and still shoot amazing at distance.
As with learning a new platform there's lots of the nuances and ins-outs to learn like most of us already know by instinct now with regular style firearms like balance points, one handed carry etc. So you can still play with balance points with these also, barrel length and weight still a factor one can manipulate, and in order to get more weight forward one needs to forgo the telescopes and the heavy triple bolt tactical rings and stick to lower talley style rings, traditional hunting scopes and keep em low enough so you can ride on standard lightweight butt stocks. So ALL of this is possible but one must learn the distinction between doing a hunting build vs the typical chassis rigs guys build up. You can get balance points where you like, you can get weights where you like, you can make very functional hunting rigs from a chassis platform.
It's a growing thing so there will be plenty of growing pains as this goes. I'm a few years in now so I've learned a fair bit so far. As mentioned the alpha mountain hunting studs doing up lots of high dollar XLR carbon folding stock rigs that are very lightweight. But you can build budget everyday working man rigs that are quite functional too and while I can afford and used to play with the high dollar stuff I no longer enjoy it, but rather the basic everyday stuff. I run a Ruger American Ranch 6.5 Grendel in a chassis now and beyond happy with the set up. It's short, stout and it's plain getting r done, very accurate, user friendly, and I was an ultralight sheep guy with 6.5-7 lb all up scoped rigs for a long time...so there's that. All I will carry now is this little bat, mountains or not, I actually like the weight, perfect would be around 7.5 all up but a little over 8 works just fine and only adds to the shoot ability. Balance is great, it one hand carries in front of the magazine well quite well, I paid attention to weight in optics/rings/butt stock/grip and buffer tube.
