The article you linked to was a very old article. I already responded to that. I would need some tests to prove that it’s still true today. The tests that I saw seemed to indicate that it wasn’t.
Philosophically, I think you are tying the behavior of UIBase too closely with the thinking behind Jewel which relies very heavily on class names and requires that users do not change that. I don’t think that’s going to be true for every component set. I completely agree with Alex’s response.
