Not all Boost libraries support C++03.  Some support only C++11 and above,
others support only C++14 and above.

The only requirement for new libraries being proposed to Boost is that they
compile with the latest C++ standard and at least 2 C++ compiler
implementations.

The thread you're seeing is about those Boost libraries that still support
C++03 that feel they cannot drop it because other Boost libraries depend on
them.

Even now, any Boost library that has no other Boost library depending on
it, is free to drop support for all C++ standard versions below the latest
(C++20). i.e. Boost library authors have always had this freedom.
