I can believe it.

I think intuitively, in terms of encoding for the file's contents the
backends should always return a byte-sequence (i.e. with no-conversion)
and the front-end should then decide how to decode it (e.g., obeying
the -*- coding -*- cookie and such).

But since that holds for all backends, ideally they should be called in
such a way that they automatically return bytes (rather than chars)
without any extra effort (e.g. without manually binding
coding-system-for-read/write).
