Ah, so "forbidding a pull of local branch" was tongue-in-cheek
comment, and what you really wanted was to allow pulling remote
tracking branch with pull, either inside or outside of a
repository, like...
$ git pull $somebody_elses_repo remotes/origin/master
without having to say "remotes/"?
That one comes from a different design issue. refs/remotes/
hierarchy is local to your repository, and is not subject to
remote operation.

My stance on this is that what I track as my upstream to
maintain my repository is none of other people's business. I
have remote tracking branches because I use them to track
others; I do not necessarily have them with an intention to
publish them.
You could pull from my remote tracking branches using the fuller
refspec ("remotes/origin/master" in the example above) if you
really wanted to, and ls-remote lets you take a peek at them, so
the above "none of your business" is not in the sense of being
secretive, but is to reduce clutter and to avoid potential
confusion.
But this is an ancient design choice, and I am open to
suggestions loosening it, as long as we are aware of
implications.
One thing that comes to mind if we allow it is if a clone should
have refs/remotes/origin/remotes/origin/* that keeps track of
the remote that is being tracked by your origin.
I think it is insane to do so, but if somebody says "git pull
somewhere-else origin/master", we would not know if he meant
remotes/origin/master or remotes/origin/remotes/origin/master.
And the reason it is "insane" is the same as why we currently do
not interpret "git pull $repo origin/master" as a request to
pull from remotes/origin/master. It really is none of your
business what kind of remote branches the other end is
interacting with.
