The implicit casting rules are different, it doesn't allow VLAs, you can implicitly create static constructors instead of having your program rejected for non-constants at the top level, more keywords are unavailable as variable names…

VLAs are optional since ISO C11, clang and gcc are probably the only C compilers that care to support them.

C17 also has its share of keywords and C2X plans to replace some of the _Keyword with they keyword version, as enough time has passed since their introduction.

Clang and GCC being the two largest implementations.

True, but not the only ones, so good luck making that VLA code work outside BSD/Linux clones or the few OEM vendors that have forked them.

Also Google has sponsored the work to clean Linux kernel from VLAs.
