On the contrary, the intent is that if you can't migrate to `-std=c++20` because `char8_t` is giving you trouble, then you can use `-std=c++20 -fno-char8_t` to migrate to C++20 **except for the `char8_t` part**. So this is purposefully supported, or at least that's the intent. Does that make sense?
