I have no idea how that's supposed to work.

Linux distros ship Boost built with the default gcc, with the default C++
standard. g++ defaults to C++03 before g++-6, to C++14 before g++-11. A
C++17 Boost will be unshippable for a while. C++14 is kind of acceptable
today.
The other major consumer of pre-C++11 Boost are non-mainstream platforms
such as z/OS, where people are still stuck with C++03.
