Definitely not.  ICU is a huge dependency, has a relatively rapidly changing API and does vastly more than is required.  The C++11 locale APIs were designed to be easy to implement on top of the POSIX2008 Locale APIs, (which were originally xlocale on OS X).  We just didn't do so in the most efficient way - the locale_t is already reference counted and so we don't need to do as much copying as we do for the facets.

My version of the draft spec says almost nothing about this header, other than it exists.
