I'd probably remove the C23 text since it doesn't seem to be completely accurate. Maybe just "Use nullptr instead of NULL."

BTW, here's the argument paper for it:

Maybe mention that nullptr was introduced in C11 spec and gcc 4.7.

coreboot switched to GCC 4.7.2 on October 25, 2021, prior to coreboot v4.1.
