I wonder how many ByteString users are `working with bytes', in the
sense you apparently mean where the bytes are not text characters.
My impression is that in practice, there is a sizeable contingent
out here using ByteString.Char8 and relatively few applications for
the Word8 type.  Some of it should no doubt move to Text, but the
ability to work with native packed data - minimal processing and
space requirements, interoperability with foreign code, mmap, etc. -
is attractive enough that the choice can be less than obvious.
