I explicitly acknowledged that:

But in fact, if speed is a concern to you, even in C you will use "templated" sorting (via macros or code generation).

The problem is that the implementation burden with C is so high, that people tend not to do it even in relatively performance constrained situations

Neither codegen nor macros (they are a part of the preprocessor) are really a part of C.

For the latter, the lack of integration becomes more noticeable if you try writing a macro in which the compare param can accept a function identifier. As the preprocessor doesn't have the knowledge of the contents of the referred function, it can't inline it. In C++ and Rust, their compilers do, so they can.

A codegen tool could overcome this, but you could also make a codegen tool to write Zig/D/C#/Swift in C, or any other language for that matter :). By this point, one could say you are programming in a superset of C, not strict C.
