I was talking from the coding point of view, rather than protocol
definition :-) Your first point is excellent (though it's an attack which
can already be performed using MX records). I think we are reaching

host name.
Right.
CSV has the major, legitimate claims to development and administrative
simplicity and to operational efficiency. We definitely should do nothing to
threaten these considerable benefits.
