Agree so far.

No, too much magic. It should take effect immediately. It’s not
hard to invoke it at the end of the form definition, but doing
so enables its use for mass-applying constraints to many, but
not all elements in the form, by calling it prior to adding the
elements that shouldn’t have the constraint in question.
