Ah, OK, I see. I wonder if that would make a big difference in practice. I expect repos to be fairly packed these days because of the I/O benefits (and even if people aren't doing it manually, we auto-gc working repos and keep pushed packs for publishing repos). So in practice by the time you got an accurate object count, you would be more or less done with the fetch (because you would have been grabbing the related blobs in packs as you grabbed commits and trees).
