Thanks for pointing this out. Can you suggest an alternative message?
Other than the mundane reason the current message says what it does
because I sometimes prefer to leave the empty file there so that when I go
back through at a later date I can re-evaluate the choice.

This sort of mechanism has been suggested before, but the problem you
described (ports installed "on purpose" becoming a dependency of something
else) is not an easy one to solve.
