Quite a few new features are still being implemented in C. Consider just the recent innovations: native-compilation, tree-sitter, support for XInput2 and touch devices, to name just a few. Moreover, familiarity with the internals implemented in C is IME quite necessary even for Emacs developers who almost never touch that layer. So the above is true only up to a point.
