The diversity of Linux distributions is one of its strengths, but it can also be challenging for app and game development. Where do we need more standards? For example, package management, graphics APIs, or other aspects of the ecosystem? Would such increased standards encourage broader adoption of the Linux ecosystem by developers?
At this point, package management is the main differentiating factor between distro (families). Personally, I’m vehemently opposed to erasing those differences.
The “just use flatpak!” crowd is kind of correct when we’re talking solely about Linux newcomers, but if you are at all comfortable with light troubleshooting if/when something breaks, each package manager has something unique und useful to offer. Pacman and the AUR a a good example, but personally, you can wring nixpkgs Fron my cold dead hands.
And so you will never get people to agree on one “standard” way of packaging, because doing your own thing is kind of the spirit of open source software.
But even more importantly, this should not matter to developers. It’s not really their job to package the software, for reasons including that it’s just not reasonable to expect them to cater to all package managers. Let distro maintainers take care of that.
