Yes, I actually have with a client I helped who tried to put in a complex passcode and promptly forgot exactly what he entered. It took about two hours with an up scaling of tech support at Apple on 1-800-MY-APPLE. We got connected with the Fairy Godmother Department who used his AppleID to unlock it. . . But he had activated that feature. It then took some time for the encryption to be redone using the new passcode.
So you have never gone the waiting period route but dispute my account
