The commit-graph could be shared, as the commits in each enlistment can
be parsed from local with GENERATION_NUMBER_INFINITY, giving us similar
speedups.
The issue is: who updates the file? As the commit-graph gets behind,
performance will degrade. But it seems like you'd need similar
maintenance on the alternate object store, anyway.
Thanks,
