If newer standards are rarely used for programming small embedded
systems, is it because the standard might have been diverging from their
requirements?
Is it because newer standards take so much effort to implement that
compilers other than GCC and clang lack the manpower to implement them
timely?
Is it because users follow a coding standard, such as MISRA, that takes
a while to update for new C standards?
