I think the concern is that last few knots with a cross wind and no more
rudder or aileron authority. But then the brake should be sufficient by
that time.

Well nice theory that better training is the whole answer, primary training is where we have seen the damage - the longer wings flown by students. The last few feet with limited contrl and the wind are a factor. So an impact ever few hundred cycles is not hard to imagine.
