It does support a light version of them via _Generic.

`_Generic` is more akin to type switches, and generics or templates generally refer to an ability to instantiate multiple functions on demand.

How the sausage gets made is not much of a problem for many.

An implementation detail how generics are exposed in C.

That is not an implementation detail of the same sort of feature. It is just a totally different feature.

OK not totally different but different enough: you cannot just write a fuction with a type parameter and expect it to work with multiple different types in C as you can in C++.
