That seems unlikely. Why would anyone who hates C put so much effort into the language. Not to mention that most people who hate C probably also hate C++ so your grouping of C++ and Rust together makes for a very unlikely alliance.

Which new features in C23 cause you so much worry anyway, most of the changes seem quite small judging by the feature overview on Wikipedia.

People from WG14 (the C committee) have complained that WG21 (C++) exerts undue influence trying to get their language to shift in ways that would be convenient for the other language while retaining its claim of "compatibility" without giving much back in exchange.

But I'm not aware of any complaints about Rust, WG21 cares what WG14 standardises because it's awkward to pretend that C++ is somehow a "superset" of a language which has instead evolved in different ways. They would prefer WG14 to take care of all the awkward low level problems they don't care about, treating it as a junior partner which is not appreciated. But Rust doesn't care about C at all and especially about the ISO document. To the extent Rust interfaces with C it's via the implementations for ABI reasons. The ISO standard may say A and B are different, but if in practice they're the same on every real platform, Rust needs to know that.
