Yes ;) an interesting one!

Today (it's late in Europe, you know... ;) I have learned so much, and I 
really concur that something must be done in this area, but, on the 
other hand, that seems a complex project *really* different from simply 
switching from widen to narrow in a facet: there are very clear 
paragraphs in the standard mentioning widen and consistent resolutions 
(such as DR 303) and thousands of users around the world reasonably 
expecting that overriding widen changes in a definite way the behavior 
of the facet, and the established role of char_traits, and...
