switch statement fallthrough in C/C++ is not an error, unless the programmer didn't intend it in the first place, but let it happen by mistake. So, I wouldn't count disallowing switch statement fallthrough as a feature.
Please allow me to introduce you to Duff's Device, which is a way of doing loop unrolling in C/C++ -- for loops with a known compile-time trip count -- based entirely on switch statement fallthrough.
Also, -Wimplicit-fallthrough both in GCC and clang.
