Yes, and it is deliberately so as it is a guaranteed-sure way for scripts to work around potential ref ambiguity when talking about the branch called 'foo' to spell it out with leading refs/heads/.

As long as you do not break scripts that guard against breakage you are proposing by saying "refs/heads/foo^0", we are Ok with the proposal, I think.
