If the intent of BooleanN is to help interfacing C-libraries.
Would it make sense to change BooleanN from being an alias to more
consistent behavior with its 16,32 and 64 counterparts?

There are chances that other libraries might benefit from Boolean8. Not
limited to ObjC declaration/use.

Wouldn't it break the compatibility with any existing x86_64 _Bool code?
If it's the same amount of work anyway, why not to make Boolean8 work as
described in the documentation.
It would save time on fixing docs for sure :)
