Sorry, I don't have those skills, or any spare time.

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.

It has worked for decades and many thousands of packages just fine.

If nobody cares enough to make the application available, perhaps it just shouldn't be there.

You still need the distro maintainers to cooperate. And the packaging itself can be highly involved (as in the case of rust dependencies on Debian)

Of course you do, that's where the value comes from after all.
