It doesn't matter, unfortunately. It currently checks even in that case
due to ON * SET DEFAULT having a failure case if you don't check when no
keys are changed (if you remove the default - and you can't necessarily
check this beforehand either if the defaults are not stable). Among the
various changes I've been working with is making it only do the check if
one of the set default cases is given or if the key changed.
