No, because the answer is that any C++11 feature can be used in new
libraries, and in old libraries too.

The critical issue is support for compilers that don't supply a
particular shinny new feature. Today most Boost developers are trying
to support all compilers that (except for export) are C++03 compliant.
A howl would likely go up from reviewers if someone submitted a
library that didn't work on C++03 compilers.

Even that isn't absolute. If a library's sole purpose was to support
or ease the use of some C++11 feature, then it might well not work on
compilers that don't supply that feature.

Boost has a bunch of feature macros in the config library to identify
which compilers have various C++11 features.

HTH,
