The idea looks really nice, and I certainly don't mind to see libarchive

My point is that there are still lots of things to be achieved before
releasing the library, and adding new features to it is certainly not
the priority right now.

There are enough backward compatibility tests between pacman 2.9 and the
library to be performed as it is for the time being...
