"Irregular" means "not conforming to the ABNF of 4646."  I don't see the 
problem syntactically with "zh-hakka".  It probably would have been made 
into a language-variant pair already, if not for the fact that ISO 639-3 
will allow "zh-hak".

There's no problem with "zh-cmn".  One grandfathered tag is the 
Preferred-Value for another.
