C only became standardized after 20 years or so, and only out of necessity because there were different compiler toolchains moving into different directions and this ensuing chaos had to be brought under control somehow. And arguagbly the standard is just as much a problem as an advantage (look at all the very useful extensions in clang and gcc which will never make it into the standard, and the C standard libary is still essentially a snapshot of what was already the least common denominator in 1989, and far from the "state of the art" even back then).

As long as a language only has a single implementation or "reference compiler" (like Rust), standardization only adds needless bureaucratic overhead.
