I think that the `binary' (better not call it "no-conversion" because
it's a misnomer if one of the ends is multibyte) coding-system should
default as much as possible to unibyte buffers and unibyte strings (so
it indeed does "no conversion" in that case).

Yes.  I've introduced the new buffer-swap-text primitive specifically to
make that possible.
