Stability rules prevent this from happening: a subtag cannot change its 
stripes, or the whole meaning of the term "stability" goes out the 
window. In that case, users would need to decide if 'zza' or 'diq'/'kiu' 
were more appropriate for their content. Another potential solution 
would be that language subtag 'diq' might be deprecated in favor of the 
prefix "zza-diq" (using a new extlang 'diq').
