They probably don't want to because then they'd have to specify how they would interact with the setjmp/longjmp functions (which are, in fact, specified as part of the ISO C standard, section 7.13 in C11).

setjmp/longjmp already interacts poorly with other commonly used language features (e.g. values of non-volatile locals upon longjmp).

In case anyone is wondering, GCC and other compilers catch non-volatile locals clobbering when you compile with -Wextra.
