+1, agreed.

I think I only made C23 equivalent to C11. Finishing the C23 conform
tests would be nice, but it is quite tedious. E.g., when I tried to add
stdint.h/inttypes.h conform tests, you mentioned that many platforms do
not yet support _BitInt [1]. There is another issue that not all
supported compilers support '-std=c23'. A new contributor could probably
figure all of this out, but I would be very surprised if they found it
enjoyable. :)
