I'm not sure why you're insisting on a deterministic encoding here. You
think MIME has deterministic encodings? The following are two perfectly
valid encodings for the same data in quoted-printable:

The point is to make the original signed data recoverable, which does
not require absolute determinism in the encoding stage.
