Ingo and I were just curious why you introduced it in the first place
(some 6 years ago)? Apparently Dano had it if the build compatibility
headers are any indication. Other than that it is more confusing than
anything else, so I'd be all for phasing it out. It is mapped to the
POSIX EOPNOTSUPP though, while B_UNSUPPORTED is simply in the storage
kit errors, so maybe there are uses where the POSIX error code is/was
relevant?
