"people don't release language updates for no reason", indeed, many reasons are in the end "planned obsolescence" or ways to make even a naive compiler so much complex that only few remains, and of course in control of very few groups of ppl, and it is near impossible to implement reasonably a real life alternative.
My opinion is C is already way too rich and complex. I would stick to c89 with benign bits of c99 and c11. The benchmark being "one average system developer coding a naive and real life C compiler in a reasonable amount of time and effort".
That said, I know that my "next" C compiler will probably be a RISC-V assembler with a very conservative usage of a macro preprocessor.
