This is where our interpretation diverges. Thibaut, could you clarify 
the situation about C++20 again? If your code requires C++20 we will 
sooner or later be in a bad position, won't we?

I propose that we activate C++17/20 on compilers that handle it once we 
have code that can use it. Bit for now, we are at C++11, we can go to 
C++14 in 2.5, for example.
