Indeed. In some transport systems, the domain literal might be interpreted
as the serial number of the loft that the carrier pigeon was supposed to
fly to.

And jbloggs@[] could be taken as an indication to the transport (not an
RFC 2821-compliant one, of course) that "I haven't a clue how jbloggs is
to be reached, but if you can figure out a way to get it to him, then
please do so".
