Note that for new libraries being accepted into Boost, the only
requirement is that (at the time of review) they compile with at least
two C++ compilers and that they at least compile under the current C++
standard (which today is C++17).

i.e. We accept new libraries that don't compile under C++11, and we
even have some libraries today that require C++14 or higher.
