That wasn't a yes/no question, but apparently clone hooks act
differently than other hooks, in this regard.  Looking at CWD would
answer your question for other hooks.

Clear ui.username from ~/.hgrc (because you don't want a default) and
then there's no longer a problem -- you can't commit without setting a
username first.

If you know how to guess the username you should use, how about a
pre-commit hook which 1) does nothing if ui.username is set, 2) sets
ui.username for the repo (if it can), or 3) prints an error message
that ui.username is not set and cannot be guessed.
