as no-one in his right mind would compile one bit with C++03 and another bit with C++17 (if you're compiling all from source).

Unfortunately, that's exactly what people do, build Boost with the default "b2 install" and then use it from C++17.

Admittedly, our build instructions don't mention the cxxstd=17 option.

Documentation is not a solution. ;)

Would it make sense to default to the highest available level?

The documentation should just say that compilers and std levels should match. In a way we have inadvertently wandered into unexplored territory (mainly because this problem never arose before). There is another gray area, which was touched upon on the list here, which I think should also be discussed more, and that's Robert's problem of linking static and dynamic libs into the same app. degski -- *“If something cannot go on forever, it will stop" - Herbert Stein* *“No, it isn’t truth.
