No, I don't think so. If I'm using hex "encoding", it's because I want to see a text representation of some arbitrary bytestring (in order to display it inside another piece of text, for example). In other words, the purpose of hex is precisely to give a textual display of non-textual data.

Or I want to encode binary data in a non-binary-safe protocol, in which case I probably want bytes. In this case you would probably choose a more space-efficient representation, such as base64 or base85.

Unless the receiver expects hex.

Please, hextext = str(somebytes.tranform('hex')) is quite easy and explicit and will work for any bytes to ascii-subset transform, not just 'hex'.

Keep .transform and .untransform simple by always going to/from same type.
