That's a great question!  I've filed https://crbug.com/git/2 to track
this project.  Feel free to star it to get updates there, or to add
updates of your own.

As described at https://crbug.com/git/2#c1, currently there are three
patch series for which review would be very welcome.  Building on top
of them is welcome as well.  Please make sure to coordinate with
jeffhost@microsoft.com and jonathantanmy@google.com (e.g. through the
bug tracker or email).

One piece of missing functionality that looks intereseting to me: that
series batches fetches of the missing blobs involved in a "git
checkout" command:

But if doesn't batch fetches of the missing blobs involved in a "git
diff <commit> <commit>" command.  That might be a good place to get
your hands dirty. :)

Thanks,
Jonathan
