There is no discussion about registering two subtags.  The discussion is 
about registering a single subtag, 'erzgeb', and giving it a suitable 
Prefix field.  Unlike subtags themselves, which can be deprecated, a 
Prefix field cannot be independently deprecated, and can never be 
removed.  Therefore, the analogy with deprecated subtags is not 

We should register 'erzgeb' only with the Prefix field that will be 
correct in the long term, which is "sxu", and that means we should wait 
until 'sxu' is a valid language subtag, which will happen when RFC 
4646bis and RFC 4645bis are approved.
