Interesting to think about just the terminology. We generally know what a "PRS rifle" looks like, because the discipline of PRS is well-defined. Same with "scout rifle", because we can use the definition that Cooper gave.
"General purpose rifle" is going to be an empty term: There is no such thing outside of a particular context. There are lots of interesting and smart setups posted in this thread, but unless you have a context similar to the poster, they're certainly not "general purpose". Not that these kinds of threads can't be interesting reading, but they tend to just get people talking about their favourite hunting rifle setups (or maybe that's your goal?).
Since you linked the Lucky Gunner content, are you asking about something like an updated scout rifle concept?
True enough, but the scout rifle was Cooper's idea of a general purpose rifle. Handy, light for easy carrying, in a powerful enough cartridge to kill man or beast. - dan
