Yes, that's certainly a possibility.  It's kind of a medium between the
two extremes I proposed.  Building based upon a direct checkout of
already patched source means all that you have to do is specify a tag
but you lose the tarball + patches.  Exporting patches from the exploded
source repo and importing them as files to the package repo is more work
but you keep the tarball + patches.  The approach you propose would mean
that the package maintainer would need to do some work to specify the
set of patches to be extracted and the order to apply them (but wouldn't
actually have to do the extraction him/herself), but you keep the
tarball+patches approach to building.

The key decision though that needs to be made is whether we take that
radical step of abandoning the tarball+patches approach.  My feeling is
that it's too radical for right now, but maybe it won't be in the
future.
