I'd rather treat C++20 modules in 2020 as C++11 rvalues in 2011. If the
compiler supports them then Boost library authors may use them in the
library and provide benefits to the end users. But they won't become a
required feature in next 20 years.

I'd expect some kind of guidelines and macro in Boost.Config as soon as we
get some compiler that properly implements the C++20 modules. Right now
there's no such compiler.
