I personally don't consider them very sane and didn't originally support
that. But this behavior is tested for in t5505-remote.sh test 27, which
started failing until I stopped warning for equal refspecs. This support
for "alt remotes" in prune was added by c175a7ad in 2008. The commit
message for that commit give a plausible reason for using them.

I agree, but c175a7ad would disagree.

Agreed and was already covered in v1.
