So what? A private-use tag has to be agreed to by the communicating
parties; in this case they'll find that such an unwieldy tag is
unusable in an encoded-word and will have to agree to use something
more manageable.  That's a problem for the parties involved and
nobody else, since it doesn't affect the rest of us.  That's a
different matter from a public tag that everybody is expected to
be able to use.

I agree that that would never be registered -- because of the
review process which is part of RFC 3066.  But the draft under
discussion has no mechanism to prevent it, unlike 3066.
