I have never flown a S/S Meteor but the T7's ailerons had servo tabs. They were light enough to start the roll going but stopping it was the problem because of the momentum of two engines. However you had a spade grip so you could use both hands to heave it around. I wouldn't dare to try a slow, or any sort of, roll close to the ground because of it's yaw instability, plus the fact you couldn't bang out.
It didn't matter too much in the fifties. Queenie had stacks of spare aircraft and nobody seemed to worry too much about the pilots.
After the Meteor they never built a fighter with the engines in the wings because of the effect on the roll performance. They were allways close coupled to the fuselage.
