There are only so many hours in the day, and my objective is to fix the issues with the C++ api. I have not spent a tremendous amount of time thinking about how to architect the C api for scalable vectors. That said, I have this patch up https://reviews.llvm.org/D78599 that provides a way to specifically get the bool from a vector, and to construct a scalable vector. If you need to be able to construct scalable vector objects via the C api, then feel free to bring this patch over the finish line or submit a patch that you feel is more in line with typical C api usage patterns.

ISTM that not supporting scalable vectors properly in the llvm-c API is no showstopper right now. But the full breakage of the fixed vector API is a real concern.
