Trade-offs in the default load-out, essentially - some of the things you want for games can bloat out the standard build, compromise the "license integrity" of the base repositories, make system instability more likely etc etc.
There is unlikely to be a time that "things stop moving" enough to make all these trade-offs go away, but you can pretty much just add all this stuff to the base distro yourself anyway if you want to (I still play games on vanilla Silverblue, for example).
Target audience favors in for default load out, too. Gamers aren’t likely to be *nix gurus and want something that will come configured correctly for their use case out of the box, including stuff like Nvidia drivers.
For this group, needing to follow wiki guides and such and spending time on basic system functionality just isn’t happening. If that’s the only option, they’re just going to reinstall Windows.
PC gamers tend to be a bit more amendable on those things, even Windows ones. Especially if they have >0 experience with modding, then they're pretty much primed for following "I don't know what this does" instructions.
I think the group you're thinking about are console gamers, who never had to upgrade drivers, never dealt with mods and generally has a very different experience compared to PC gaming.
Well, you also have those who are capable but not necessarily willing.
I’m increasingly leaning that direction. Day job is software dev, have been using and/or tinkering with some form of *nix for almost 25 years, and have been using computers for even longer and sometimes I just don’t have the patience for fiddling around with computers to coax them into doing what I want them to.
