GCC is still expected to bootstrap from a C++11 compiler. (For self-hosting compilers, language version choice is not only about useful language features.) The built compiler defaults to C++17. I think the remaining obstacle before moving to C++20 by default is more experience with (and fewer bugs in) the support for modules.
