Nothing, but I'd expect getopt(3) semantics for any command's one-letter
options where a dash is involved in the options. Whether --unlink works
with the old style options is not for me to say, but since the double dash
GNU options are extensions to getopt, I'd expect to have to use dashes with
the rest of the options on the command line.

The latter sounds better, because it could be used in a single dash
environment too, and would be nice to have for the next thing you mention:

Dunno; OpenBSD did this at one point, and they had a lot of "cleaning up" to
do to get it to work just like tar. :)
