Yeah this is not a bad idea. It would reduce need for complexity in

The problem is with the PKGBUILD design. It wasn't really designed for
multi-architectures, or even for fully supporting source builds. I don't
really like the idea of building hacks upon hacks upon a format
ill-suited for current needs.

Yep. In terms of metadata I guess a good first step would be to use some
simple clean format that is meant for data, not execution. Maybe
pkginfo, (pacman db), yaml or something.
