This won't match in the case where DC thinks what looks like a fast update to DM is actually a medium or full - like scaling changes that affect bandwidth and clocks. [How] Drop this warning. DC knows better than the DM does for determining cases like this. The other warning can be kept for now since it would warn on a pretty serious DC or DM bug.
