I would not have said that BCP 47 "twists" the core standards in any 
way.  I would have thought it would be the other way around: we would be 
"twisting" the standards if we picked some of their code elements and 
discarded others, or added new non-private code elements, or did 
something else in violation of the provisions of the standard.

For the most part, we use code elements from ISO 639 to represent 
languages, from ISO 15924 to represent scripts, and from ISO 3166 to 
represent countries.  That doesn't seem like much of a stretch to me.
