these features will eventually trickle down into the mainstream, kind of like C11 is doing at the moment also, unless you're targeting embedded or a very wide set of architectures, there's no reason why you couldn't start using C23 today

Or in other words, for embedded and existing code: most use c99, some use c11 and nobody uses c23 until at least 10 years from now.

  most non-embedded and non-legacy codebases could use c23, that's not an insignificant set

    I would argue that is an insignificant set. Unless you think that code-bases created in the past year are a significant part of code bases that have been created since the inception of humanity.

  This depends on the platform. Many embedded systems are based on arm these days and have modern toolchains available. I cannot remember the last time I saw C99 used. C codebases generally use C11 or C17, and C++ code bases use C++20

    Unless you can vouch for the C++ compiler, the best C++ portable code can offer today is C++17. Also 8 and 16 bit embedded toolchains are certainly not on C11 / C17, they can hardly afford full C89.

      SDCC is a niche C compiler for 8-bit CPUs and is more uptodate than MSVC ;P https://sdcc.sourceforge.net/ https://sdcc.sourceforge.net/ That's the nice thing with C: it's much easier for small teams to fully support than the latest C++ standards.

        Now try to use it on the embedded deployments that require certification.

    Most devices that are 6+ years old (as far as I can tell) use C99. If not C89. And/or C++17, if that. That's A LOT of devices out there. A lot of which still get maintenance and even get feature updates (I'm working on one right now, C99). So the claim that "C codebases generally use C11 or C17, and C++ code bases use C++20" intuitively sounds like totally untrue to someone working in embedded C/C++. I've been doing this for 15+ years and I've never touched anything higher than C99 or C++17. If you're talking about gaming, sure. But that's not "C code bases generally".
