The major argument for me to NOT include mapping in IDNAbis is that  
IDNA(bis) is context free, while mappings that people want to have  
(given the requests I have got for example) require context dependent  
mapping. For example based on what locale is in use.

That one might need well defined mapping mechanisms is of course  
clear, but it can not be resolved as part of the context-free domain  
name layer in the chain of functions between user and wire.
