I'm not so sure about this. The reed warps along the length and there's nothing to stop it where the bark has been cut. If anything the thinner wood is more likely to bend. Curling even slightly up at the edges of the vamp away from the rails should cause stress that I would think affects its vibrancy, and any curve away from the rails at the tip would result in the center of the tip closing against the tip rail while the corners are still free, causing weird response problems (one symptom of a warped reed). The amounts of distortion away from the rails is very small, maybe not always visible, but those upward stresses on the edge fibers toward the center exist.

When you do a suction test to detect a warped reed, I've always assumed the failure to produce a suction comes from the force of the curled edges away from the rails. The reed doesn't hold against the rails (to form the closure) because the force of the warped cane pulling away from the rails is greater than the outside air pressure pushing in on the reed when you evacuate the chamber.

Mostly intuitive speculation - I have no proof to back any of this up.
