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.
