I've already heard you say the above elsewhere, but I am not
sure what you exactly mean here.  Mind substantiating it a bit
more clearly?

I think "ls-remote --heads ." is just a special case of giving
"refs/heads/*" as the glob pattern:

        $ git ls-remote --heads . | head -n 3
        3545193735522f733fdb4e345f16ddf131e2007a	refs/heads/ap/ident
        b7993dd57a9cfd5b989f0e2cc5d271a524339318	refs/heads/db/remote
        960ccca6803c9fb57429d43572a9545a96107e32	refs/heads/dh/pack

	$ git ls-remote . refs/heads/ | wc -l
        0

	$ git ls-remote . "refs/heads/*" | head -n 3
        3545193735522f733fdb4e345f16ddf131e2007a	refs/heads/ap/ident
        b7993dd57a9cfd5b989f0e2cc5d271a524339318	refs/heads/db/remote
        960ccca6803c9fb57429d43572a9545a96107e32	refs/heads/dh/pack

	$ git ls-remote . "refs/heads/???/*"
        7841ce79854868eaaa146c1d018b17fc4f3320be	refs/heads/mst/connect

        $ git ls-remote . "refs/*/jc/*" | head -n 4
        80a767ba3b1c69fc41fa5f5fbe4a247757a9c575	refs/heads/jc/blame
        a1481ab7b16c51d4ec7925fd9b38d9cf21f72263	refs/heads/jc/diff
        4e8daa0dca5deb9d391538241939a2a2ad6d36b8	refs/tags/hold/jc/3way
        ff77ab7919e6f31cb6c58bc004217e624b553fb6	refs/tags/hold/jc/changes

So if you really do not want separate interfaces, I think you
could just implement --heads as what it is: a shorthand for
"refs/heads/*".
