In fact outside of ultimate, there would be no reason to cast any healing GCDs. You're never in this scenario you mentioned at the end if everyone was playing optimally. Using a GCD heal to rectify a mistake will never be seen as optimal play.
You're conflating optimal group play with optimal individual play. Optimal group play is never needing to GCD heal in any content after ARR because everyone's on top of their game. Optimal individual play, on the part of a healer, can mean GCD healing to rectify the mistakes of another individual not playing optimally, to prevent the greater DPS loss that would come of letting them die.
