I'm also interested in the concept of a C++11/14 only boost and what that would mean. I've been hoping the git migration would finish so that working on that locally would be more feasible rather than having to deal with either svn or git repos that are constantly changing. Granted, I would probably go far enough to suggest removing or deprecating libraries that are part of the standard and isolating them as much as possible while they exist.
