I think yours is a canonical example of "I do not want to run
command X when these conditions hold", when "these conditions" can
be checked locally _before_ you decide to do X.

While it is theoretically possible to give X a pre-X hook in such a
case, we do not want it to be the first choice to avoid hook bloat.
