The reason I would like to avoid .git/remotes/$origin is because

C-level is prepared by the upper layer using that file.  As far
as I understand, Cogito does not understand it either, except
that it ships with bash completion code that reads from
filenames there.

Then why not create .git/refs/remotes/$origin/HEAD at the time of clone
(or later)? Then the core looks for:
  (current order, .git/refs, etc)
  .git/refs/remotes/foo
  .git/refs/remotes/foo/HEAD
The porcelain can take care of managing the contents of HEAD. If there
is no HEAD in the directory, then it cannot be looked up by 'foo'
('foo/remote-branch' must be used instead).
