If I remember correctly, I think that's the answer HT gave on this issue a while back, since the consistency of flap use over certain speeds will have to be maintained. HT said they can implement it, but they will just have to implement it so that the flaps get damaged over designated speeds.
The only instance I ever read about this specific issue was in the Hurricane MkIIc Pilot's Manual. It says, if the plane flies over the recommeneded speed with the flaps out, the flaps will be forced partially shut by air pressure, and if it is deployed at those speeds from a clean state, it might not pop out fully. But it doesn't say that the flaps will be damaged.
I don't know.. maybe it's possible to put in a certain 'safety margin', like maybe 50~80mph? Maybe n the 'margin' set, flaps will be forced shut partially, like the Hurri manual indicates, and its efficiency will be reduced. If over the 'margin' speed, maybe they'll get jammed or something.
