For that we'd also need a way for clone to be able to fetch just a
single branch, and not all of them as well.

There is some clone vs. fetch asymmetry here that has annoyed me for a
while, and that I don't think has been mentioned in this thread
yet. Namely:

clone: can only be executed once, fetches all branches, "remembers"
       URLs for later simplified use

fetch: can be executed many times, fetches only named branches,
       doesn't remember anything for later

I've often been in the situation where I cloned a long time ago, but
I'd like to be able to fetch everything that I would get if I were to
start a fresh clone.
