I believe Shuttle did at pad release/liftoff. Because by then it is no longer on the pad but a vehicle in flight. Once it was released KSC had no way of controlling it beside having the range blow it up.Tower clear is no longer a relevant call
Wasn't "Tower Clear" used at one time to mark the moment when control shifted from KSC to JSC? Or does the shift now occur a at pre-defined number of seconds after liftoff? Perhaps SLS has its own timer for this.
