True, my bad I didn't realise that for patches, Git won't have a problem
with that, even though it seems obvious in retrospect.
A different problem would seem to be updating, or at least a "git pull"
would download the entire repository.

I find these claims difficult, since as mentioned before, the intention
behind writing package-vc is not just to install a package from a VCS,
and judging it as such is misguided IMO.
But feel free to work on it, I am not opposed to patches that wouldn't
violate the fundamental intentions behind package-vc, but I suspect that
the end-result will be a more advanced version of the command I provided
below.
Also, if you intend to work on this more seriously, we should move the
conversation to the bug tracker or private correspondence for the time
being, where we can discuss details and ideas.

I am not familiar with Gentoo or why they build from Source (my
impression has always been that this is partially motivated by a
performance concern, and the ability to compile optimised executable
for the current system?).
