Then you can be the one who'll package it for your distro.
And if you want a system whereby software only gets made available if distro-providers care enough, then that's fine. But you're putting a filter between the software producer and non-technical users, and you should be aware that this is a choice you're making.
If nobody cares enough to make the application available, perhaps it just shouldn't be there.
And yet insane quantities of programs used by millions are only available via raw .deb file downloads, or random alternative PPAs, or via programming language package managers.
The distro maintainer system is impressive, and I’m thankful for it. But saying “it has worked for lots of packages” says nothing about the many it has not worked for.
