As a sneering C++ programmer, why are you even reading / commenting on a new C standard? This is basically a "if you don't have anything nice to say, don't say it" situation.
Honestly, because there's very little c++ content here on HN and a relatively large amount of C content. Most of the C content is full of people saying "we don't need X from C++" but the reality is most of these things have significant uses
Neither of those statements really matches my experience with HN (high C to C++ content ratio, lots of comments rejecting advances first added to C++). I totally agree some of these things are very useful and I'm glad to see them formalized in C (even years later than C++).
They're too busy looking for their vowels to reply here.
Joking aside, I've a healthy amount of respect for rust, and I hope that many of the ideas make their way into other language. The terseness, heavy use of macros, _insane_ compile times (and that's coming from someone who writes templates in c++), general assumption that you're on Linux from third party crates, and IDE support combine for something that just isn't usable for me just yet. Maybe in a few years!
