This is also my interpretation. For this reason, I don't think a change is
necessary.

All good questions to ask.

Absolutely.

So, if such a feature were available, wouldn't it be nicer if the initial
clone set up the refspec like this:
[remote "origin"]
url = git://git.kernel.org/pub/scm/git/git.git
fetch = +refs/heads/*:refs/remotes/origin/*
fetch = refs/heads/maint:refs/remotes/origin/maint
fetch = refs/heads/master:refs/remotes/origin/master
i.e., the non-wildcard refspec are about which branches are *not* expected
to be rewound rather than the other way around.
