I played with making a git alternative that was streamlined according to workflow. I haven't completely abandoned it, but my core idea was that you can use ast path to compress the data further.
Like you said git is really efficient, and even though I went in with some criticism because of the work(mess) that is chromium and the deep hacking I did there to fix stuff between versions without forcing a complete rebuild
I think my layer could be useful in the future as a queryable layer and compression plugin for git code. Anyway here's the attempt: https://github.com/pankon/gat
It can get even smaller when loose objects get packed into packfiles because of delta compression: a whole bunch of identical files can be stored in minimal overhead over storing one copy.
