I am currently using Linux Mint (after a long stint of using MX Linux) after learning it handles Nvidia graphics cards flawlessly, which I am grateful for. Whatever grief I have given Ubuntu in the past, I take it back because when they make something work, it is solid.
Anyways, like most distros these days, Flatpaks show up alongside native packages in the package manager / app store. I used to have a bias towards getting the natively packed version, but these days, I am choosing Flatpaks, precisely because I know they will be the latest version.
This includes Blender, Cura, Prusaslicer, and just now QBittorrent. I know this is probably dumb, but I choose the version based on which has the nicer icon.
You’ve just moved the packaging problem from distributions to app developers.
The reason you have issues is historically app developers weren’t interested in packaging their application so distributions would figure it out.
If app developers want to package deb, rpm, etc… packages it would also solve the problem.
