My understanding with the Mercurial stuff at Google is it was done that way because Mercurial defines a wire protocol, while Git does not (it expects a filesystem). So when fig was put together, they simply couldn't use git for the intended workflow, because it needed to be able to front-facade the existing CitC/Piper repository.

Prior to that, we used to use 'git5' which was kind of git bolted on in front of Piper, and it worked, but it was a little wonky with explicit import and export steps.

I tried to use fig a little before I left, and I can't say I was entirely blown away. I used to like Mercurial a decade and a half ago, and learned it before git... but it felt very foreign to me now.
