Hmm, commits require a working tree so if you really want to forbid some
stuff you need to do that where the commit happens: the dev's machine.

That's because the commit already happened, you're dealing with
revisions at this point. You can only forbid *merging* or *pushing* revisions
with forbidden stuff.
