Most important aspect of C is its portability. From small microcontrollers to almost any computing platform. I doubt that any new version of C will see that much adoption.

If I want to live on cutting edge I would rather use C++2x or Rust rather than C.

Am I missing something? What benefit this supposedly modern C offers?

The `thread_local` specifier is used on a few microcontroller platforms already, but would be absolutely illegal in C11 and before to use. However, it vastly simplifies memory management in a threaded context.

Why would I rather step into the world of C++ just to deal with that?

IIRC, performance and cost of thread local store varies greatly between platforms.

You have to know what you're biting into, before you use that.
