That's a very odd use of the term. Is it just you? In my experience
the term has always referred to an aggregate of multiple bits (usually
enough to store some system-dependent idea of a character).

The only bit-addressed hardware I know (the famous Burroughs machines)
freely uses the term byte. There are 8-bits wide.
