I think it *is* worth asking "what's the point". 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...

I believe Stephen Kelly has posted on this list a couple of times about how CMake tries to address these issues.
