I'm a bit out of touch, but I'll have a go.
Standard profiles arose because even though AN and QF operated the same types, they operated them differently. This caused sequencing problems (and as they went everywhere in pairs- in the true spirit of competition- something had to be changed).
The "resume standard profile" I think you are referring to is actually "resume profile speed" or "resume normal speed" which releases you from a speed restriction, but means you must still comply with STAR speeds etc.
Someone more current may correct me.
