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?
There was the Linux Standard Base project, but there were multiple issues with it and finally it got abandoned. Some distributions still have a /etc/lsb-release file for compatibility.
