For end users whether a particular library uses c++11 features is more-or-less irrelevant - they have a set of real world compilers to support (or justify upgrade from) and so they would love clear statements about what compilers a particular library works on. Of course it is not trivial for an author to supply such a statement - bits of the library may require more modern c++ than other parts - or the minimum feature set required may be inherited from a library used internally by the implementation and this might also change from release to release...

If the modularisation of boost takes shape then if would be useful to have C++11 libraries NOT unnecessarily depend on the boost version of C++11 libraries in order to reduce dependencies.

What’s your view on that?

E.g. if I wanted to make a "boost C++11 random library” then that could build on top of the C++11 random lib instead of the boost random lib. This would reduce dependencies and make the library work standalone on a C++11 compiler.
