Not to fully encapture C's variadic printf, but on the macro front, I've been having fun creating type checking for macros by a constexpr allocation from a _generic switch type check of the args and then checking the result with static_asserts. I think there was a hack before as you mentioned but would have to dig through my tests to find it, but the C23 version is quite clean. Might want see if I can get it to be clean for a variadic printf version.
