From my perspective as a Git user, not developer, git-rev-parse is
between plumbing and porcelain, but much more plumbing. It's listed as
porcelain but is connected to the plumbing git-rev-list, and for the
most part it does things incomprehensible without understanding Git
internals. Then it also has a bunch of options that are very useful in
scripts but unrelated to revisions, here I mean --git-dir or
--is-inside-work-tree.

I'd be happy to submit a documentation patch for discussion that
formally moves rev-parse to plumbing.

Agreed, so I'm very much inclined to move forward with Junio's preferred
solution on this, which would also act differently by only outputting
the branch when you're really on a branch, and being silent in e.g.
detached HEAD.
