Not sure to be honest, but, if so, I think we would covering cases like
that with the proposed change. IMO, if we depend on PHYs being
active/non-active, we should track that to in pmdemand_needs_update() be
safe.

One scenario I could think of is an update to switch connectors while
keeping current pipe configuration.
