Apologies, I don’t understand. Is any modern Linux distro lacking “general usability” or applications? Anyway, for Bazzite, there’s a bunch of ways to install software. (Though I haven’t used it myself.) I’m also not sure what you’re looking for when you’re saying “support”. Good documentation? A helpful community? Continued active development?

Just because there’s a strong focus on gaming doesn’t mean the distro would suddenly do bad at everything else, especially… general home/office use. Linux is good with that across the board. I hope I didn’t misunderstand. Please explain.
