NACK, and the rationale expressed as a question:

If unique compatibles were required to determine the power domains to which
devices belong, we would have accumulated numerous additional compatibles for
every IP block used on new systems with even slightly different power-domain
configurations—a scenario that occurs frequently. Why, then, is such a
requirement considered necessary in this case?
