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.
