The point is, it's ok at a full ATC airfield, but not at one with AFIS or air/ground, because they are not permitted to give instructions to aircraft in the air. To do so at an airfield in the UK (at least one with an ATZ = busy) is an airmanship problem and definitely not good TEM. We had a visitor just last weekend who did one after starting a base turn, he created havoc but the FISOs were pretty helpless due to their restrictions.
