You'd like to think so. But "Deprecate TIBETAN THINGY and add TIBETAN THINGY BIS so that we can fix the problem" is utterly ridiculous.
And by that I mean, given the TWO standards Unicode and ISO/IEC 10646, adding duplicate characters is frowned upon, so it should be less preferable than UTC fixing broken classes if they really are broken.
