Indeed, it is a very good point.

IIUC, the 5th one is about fetching tons of refs that you have never seen, right? If a repository that has trouble with everything-local is suffering because it right now has 300k remote-tracking branches, I'd imagine that these remote-tracking branches are being added at a considerable rate, so I'd not be surprised if these "new" refs benefits from that patch. And it would be nice to know how much a real life scenario actually does improve.

Thanks.
