Suppose you have three proposed optimizations, all of which save the same amount of power. Change A requires no modeling changes, change B requires modeling changes with well understood impacts, and change C requires modeling changes where the impact is unknown. If you could only implement one, your priority would probably be A > B > C.
Since it's not clear to me what the consequences are on the modeling here, I'd put this in category C. If lots of people start using it, it could move to B. The ideal would still be A though.
