BTW, here's the opinion of the GCC devs:

Don't ever use the -std= option to raise the language from the default. That 
implies opting in to functionality that they're not entirely satisfied with, 
and may possibly still break ABI.

Considering GCC 13 still defaults to -std=c++17, we shouldn't raise our 
minimum to C++20 until at least GCC 14 can be made a requirement. So I'm going 
to guess not before 2027.
