We should move away from it in C usage as well.

Ideally, the standard would include a type that packages a string with its length, and had functions that used that type and/or took the length as an argument. But even without that it is possible avoid using null terminated strings in a lot of places.

The standard C library can’t even manipulate NUL terminated strings for common use cases…

Simple things aren’t simple - want to append a formatted string to an existing buffer? Good luck! Now do it with UTF-8!

I truly feel the standard library design did more disservice to C than the language definition itself.
