I don't think it has at all.
I've done many hundreds of training hours over the last 5 years and never considered anything I was involved with as tactical larping. As just an everyday CCW guy, all pistol training was all done from concealment with what I EDC.
Rifle training was minimal in comparison to pistol, medical and tactics/thinking training because frankly fighting my way to a rifle is tactical BS in my EDC urban setting. Plus rifles are way easier to shoot well after long layoffs and having good pistol (ie raw shooting fundamental) skills all but guarantees solid proficiency on a rifle, but none of that is quite as true when reversed due to their inherent cheat mode.
90% of all firearm training is about the fundamentals. Advanced training is mostly just doing the same fundamentals only better and more efficiently, while also adding in problem solving tasks, changing environments, and working against thinking moving targets. All that is pertinent to everyday concealed carry.
Now if someone else has been prioritizing things like team door breaching and hanging out in ghillie suits over improving their raw shooting fundamentals and working on realistic scenario problem solving while claiming it was all relevant to their CCW and suburban HD lifestyle, then yeah maybe they should reevaluate their training needs.
There is a potential purpose to all of it, it's just that some should probably prioritize the different areas of training in a more logical order. I've seen a few people running through shoothouse training or running and gunning against big steel like billy badass, that were really bad when it came to actually placing rounds where they were expected to go under more realistically narrow accuracy expectations when hits were evaluated on paper. They apparently skipped past training in good fundamentals and went straight for the showmanship.
