Do you think libc is also written in pure ISO C?

I love how language extensions, and subsets are always valid for C and C++, but used as an attack against other languages, as if to prove they are not good enough for a specific use case.

Well, neither are C and C++, as they either have to rely on hand written Assembly code, language extensions, or be gutted down into subsets outside the official language standard.

Ultimately, it comes down to the (subjective, sure) ergonomic limitations of a language. To me, Go without garbage collection and implemented using specific compiler support and significant amount of unsafe operations, does not really represent Go, just as, so to speak, a Rust project containing 90% unsafe code does not really represent Rust. Both are possible of course, and there are even use cases in which they may be desirable in the broader context (ie. the Go runtime).

Therefore, this is not an attack on the language; it is simply an assessment of its ergonomics for particular use cases.
