[pacman-dev] Versioned packages

Here is my attempt to solve seven years old infamous problem:
Patch won't solve problem out of the box, a small changes in kernel PKGBUILD
will be required, but only concerning install part.
Idea behind patch is pretty simple:
1) Configure list of packages and number of old versions pacman should try
2) When upgading to new version, keep old in place, if it has no file
conflicts with new one, and mark it as `archived`, remove oldest `archived`
Most of time pacman treats `archived` packages as if they aren't installed.
For now it won't check package conflicts and dependencies, only file conflicts
with newer versions. It's only an outline of full solution, proof of concept
to illustrate the idea.
I'd like to hear opinion of community whether this problem should be solved
at all, or is it more like a feature of ArchLinux, and if it should, whether
such approach suits ArchLinux's philosophy.
