It is one out of many since 1958, starting with JOVIAL, how the industry has been aware of the security flaws that C allows for, which WG14 has very little interest in fixing, including turning down Dennis Ritchie proposal for fat pointers in 1990.

Note that C authors were aware of many flaws, hence why in 1979 they designed lint, which C programmers were supposed to use as part of their workflow, and as mentioned above proposed fat pointers.

Also note that C authors eventually moved on, first creating Alef (granted failed experiment), then on Inferno, Limbo, finalising with Go.

Also Rust ideas are based on Cyclone, AT&T Research work on how to replace C.

It was needed the tipping point of amount money spent fixing CVEs, ransomware, for companies and government to start thinking this is no longer tolerable.
