The difference is that guest-file-read/write have the payload in JSON;
for file-based secrets the payload is not JSON.
So I think that "binary" (which is the default anyway) would fit all the
usecases (direct over JSON, file-based, direct over command line).
Direct over JSON would be limited to valid UTF-8, but that's just a
limitation of the transport.
