No MaxT.
Washout is not for high speed stall. It is for any stall (high or low speed). The idea is to allow the ailerons to function when the stall is impending (some of the wing stalled).

The F-18 is a perfect example of what I'm talking about. The aircraft has flaps and ailerons. Don't forget it also has a complex flight computer insuring the pilot doesn't lose control at lower speeds. The flaps extend and so do the ailerons but you will notice the ailerons have less deflection than the flaps when needed (impending stall (high or low speed).
If a wing begins to stall at the root it is much easier to recognize and correct before control is lost. Whereas if it stall first at the tip and aileron, control is lost before the early warning signs of stall occur.
