Irrelevant.

AFAIU, you think that the logic of delegation

  your mode --> some-other-mode --> text-property(font)-ification

is somehow sufficient to free you from caring about time-related
issues.  Wrong.  Given that WHATEVER-ication would usually (or often?)
run in a time-delayed hook can't be ignored.
