Then what's the point in having different distros lol we don't have duplication for the sake of duplication there are reasons why there are different distros, philosophies and packaging method. I see this mistake from many usually newer Linux users, there are different distros because there is a point in packaging the OS differently.

Flatpak for example completely abandons makig apps use patched system libraries. Or having different packages for different init systems. Or , god forbid, supporting BSDs
