For bitfields we usually use enums (e.g. https://github.com/llvm/llvm-project/blob/main/libc/src/stdio/printf_core/core_structs.h#L34)
As for `ADT/BitFields.h` we could potentially create a version in `__support` if it's necessary/useful.

For the public API, I don't have a strong opinion on whether it's opaque or not.
