However, if INDEX, WORKTREE and EMPTY are preferred as syntactic sugar

the future.

Implementing INDEX and WORKTREE would be quite challenging. EMPTY is
easy because it is really just a fake ref for a particular sha1. The
others need special casing everywhere that might look at the result.

So certainly if you want to do EMPTY, I wouldn't let the lack of the
other two hold you back. The only reason they are related at all is that
they would probably share a syntax, if the other two ever even get
implemented.
