Personally I do not think you should feel embarrassed at all.  I
didn't know it myself, and I do not recall designing such a
behaviour, so I would not be surprised if it is merely what the code
right now happens to do.  FWIW, I would have expected that a "git
push origin HEAD" when HEAD is a symref to a branch 'x' would behave
as if "git push origin x" were given, going through the usual
simple/upstream/matching etc. dance.

Do we consider the current behaviour useful?  Is it documented
already and widely known?  If the answers are yes/no, of course we
should document it, but if they are no/no, it may not be a bad idea
to deprecate it and replace it with a saner version (i.e. deref HEAD
to branch name and behave the same way as pushing that branch) over
