Can you indicate whether the proposals were for is initData format
identification, isTypeSupported, or both? Aren't these two things somewhat
independent: the first is the format of the initData, while the second is the
format of the entire container + video + audio + content protection?

Note that some format specifications will have already defined such a string,
e.g. video/vnd.dece.mp4 for CFF.
