I will just have to disagree with you and say that none of the reasons 
which you give is going to make me add C++11/C++14 code to a software 
library, Boost or otherwise, or an application.

It is then not a matter of not being able to use an STL11 equivalent but 
only of the work involved to do so. If there is a reason to use 
functionality provided by C++11/C++14 a Boost library may still decide 
to do so. There is nothing technically holding back that library from 
doing so.

I do understand your point of view about new libraries using C++11/C++14 
in order to cut down on dependencies of the equivalent functionality in 
Boost. I do not think your point of view is lost on anyone following 
this thread and your arguments. But that is a decision which each 
library developer will make.
