With coupled regulators you might have something kicking in because a
change was made on a completely different regulator... If we don't take
account of coupling requirements we'd doubtless have issues with that at
some point.

I don't follow? What would a "constraint" be in this context and how
would it be different to the voltage range you'd set in normal operation?
