You will complicate controller's work if you do not slow down quickly
It seems equally true that you will complicate a pilot's work if you do not give a speed restriction in good time such that it can be met without the use of additional drag/noise required to slow down quickly. You'd not advocate driving up the tail of a traffic queue and applying the brakes sharply I suspect, just lift in good time.
Exceptions such as other traffic not behaving as instructed etc I understand, just offering the other side of the coin for that statement.
