No objections to changing this, but I don't think it's the fault of a
commit message if someone reading it doesn't get an explanation for a
future unrelated improvement.

The times when a commit should have such an explanation are cases like
e.g. introducing a function that's not used yet to make a subsequent
commit smaller, or other such cases where the change is incomplete in
some way.

Deliberately omitting an obvious improvement "while at it" would be
similar to adding a function that is not used yet.  Careful readers
notice "why don't do it at this step while touching the same area?"
just like they would notice "why do it at this step when it is not
yet used?".  While it certainly is *not* required, they would find
it helpful to answer such questions, erring on the safer side.
