People chose C because they liked C. Of course they don't want C to change. The only thing the ISO committee should be adding is stuff for filling in the holes in language (C23's Improved Tag Compatibility and __VA_OPT__ are good examples), not add features that were never part of C and were never supposed to be there.
Your question can be reflected back to you: if you want an ever changing languages, go to Java, C# or C++, why mess with C?
