I just couldn't think of a use case for it and so didn't want to
introduce a feature that we might have to support in the future then.

It is bytea because it should be thought of "just some data". It
should be regarded more as a token than as text and should not be
inspected/interpreted at all. If anybody decides to do so, fine, but
then they should not rely on the stability of the message format for
the future.
