I am not saying that a controller shouldn't restate a requirement if it gives warm and fuzzy feelings all round, what I think is though it is a safety issue that a requirement should not be cancelled by default, but have to be specifically cancelled.
I mean if you need another example, I am vectoring a gaggle of aircraft for spacing, I have reduced everyone back to 250 kts and as I take the aircraft off the headings and route them direct to the arrivals gate to pick up the STAR each of those aircraft can disregard my restriction to maintain 250 kts IAS and fly whatever speed they like now cos I have recleared them. Yeh that is a workable situation
