The wording you're using seems inconsistent to me.. Specifically,
you're saying that x.7.30 means one thing when attached to a
200-series reply, but the opposite when attached to a 500-series
reply. I would prefer to see two separate codes if you're going to do
this.
But the bigger question is implementation. Who would make use of
this, either as a sender or a receiver?
a receiver could assist a sender in adjusting its egress mail process
without the need for the receiver to collect a lot of DMARC reports and
analyse them. A sender could use it to improve its outbound mailflow. I
doubt however whether anyone will implement this as it assists possible
adversaries as well...
