11. nullptr for clarity and safety.

You also need to include some header (which one?) in order to use it.
I'd hope you wouldn't need to do that for nullptr, but backwards
compatibility may require it (because of any forward-thinking
individuals who have already defined their own 'nullptr').

 It is bold, perhaps, but there are certainly good reasons.

Perhaps go bolder and drop the need to explicitly include those 30 or so standard headers. It's ridiculous having to micro-manage the availablity of fundamental language features ('uint8_t' for example!) in every module.
When I suggested this is the past, people were up in arms about the overheads of having to compile all those headers (in 2017, they were 3-5KB lines in all for gcc on Windows/Linux).
Yet the same people think nothing of using libraries like SDL2 (50K lines of headers) or GTK2 (350K lines).

This does mean that some pre-C23 code will be incompatible with C23.

This was also my view in the past, to draw a line under 'old' C and to start using 'new' C.
I understand C23 mode will be enabled by a compiler option (-std=c23); the same method could have been used to enable all std headers, and for that to be the default.
Hello World then becomes this one-liner:
   int main() {puts("Hello, World!");}
