I haven't written much C, and I don't have a firm opinion on whether or not that particular issue is C's biggest mistake. I do think that just this one change sounds radical enough, as far as the effort it would take to convert existing C code that uses the high-risk pattern, that it seems better to just wholesale convert to a language that already mandates safety like Rust or Java. Particularly when you consider all of the other high-risk patterns in C that these other languages eliminate.
