The other point pilots would do well to be aware of is that in busy environments as a controller it is important for us to have the aircraft vacate the levels to make room for other aircraft coming in behind. Hence the instruction which permits the aircraft to stay at speed til it reaches FL150.
I always remember the phrase, "you can't expect the aircraft to slow down and go down."
