Yeah, that sounds sensible.  Start with a "'git rm -u' is forbidden
without arguments", give advise to use either "." or ":/".  And stop
there.

The first step of "git add -u" migration plan would be to warn when
no argument is given and update all the existing index entries, and
give the same advise to use either "." or ":/".  Keep this for three
cycles: 3 * (8 to 10 weeks per cycle) = 27 weeks ~ 1/2 year.

The second step would be to forbid "git add -u", and keep the
advise.  That will make it in-line with "git rm -u".
