Not even that.  We don't register macrolanguages per se; what we do is 
register primary language subtags, some of which correspond to ISO 639-3 
macrolanguages.  The only difference between these and all the other 
primary language subtags is that some (but not all) of them may be 
followed by an extended language subtag.
