In my very humble opinion, I think it will overall cost less energy
if we let changes like this go in, and deal with the odd case where
the change is not obvious after all. My reasoning is that these cases
happen very seldomly as the global maintainers have demonstrated a good
sense of judgement, and it's always easy to revert if we need to discuss
this.
