But this is mercurial. Or rather, it's mercurial rebased on top of the git data store, and it's a fork with breaking changes so it has a different name.

I do agree that the requirement to be online gives me pause. But I guess I don't know how much of a problem that would be in practice, since there's a mystery subset of functionality that works disconnected.

For us external people, it seems like it's mostly for using the hg interface with a github-hosted repo. The internal reason appears to be scalability to massive monorepos. Since I much prefer the hg interface to the git interface, I'm good with both of those motivations.
