But "git-gc" without the --prune doesn't delete any objects. So it should always be safe to use git-gc even if there are repositories that are relying on that repo's ODB. It's only if you use git-gc --prune that you could get in troudble. It might delete some packfiles containing objects needed by B, but only after consolidating all of the objects into a single packfile that contains all of the objects that had always been in A's ODB.

So I don't see why this wouldn't work.
