C++ standards committee should forget about 50+ year old computers. There's indeed couple of people around the world maintaining ancient software, but those people have not updated their compiler for decades. Nobody will try to use C++20 on those systems. It's safe to drop them.

bro just assumed a byte (aka a char) was 8 bits 
he doesn't know that the C standard only mandates a minimum of 8, and that you could indeed create a platform where a byte is 9 bits and have a valid C compiler implementation
