Would you elaborate in which way the requirement is "hard"?

An implementation of va_list is not itself a part of the calling
conventions, it should be possible to use whatever mechanics the compiler
chooses, builtins, macros or inlined/static functions.

Is the limitation like "no support to avoid a certain definition of
va_list which is hidden inside the standard includes"? Then in theory
it could still be worked around, by using a modified copy of up to
all the system includes (which would be not pretty but possible).
