Yep… And the easy recipe for one which doesn’t care about RPKI to restore reachability is “delete the ROAs”.

I have no impression that it was.

I thought it was about “Should we consume more RIR resources dealing with this additional pain likely to be caused by RPKI?”

I agree with Mr. Morrow that this would end in pain.

Agreed. However, whether I liked RPKI or not, I’d still say that notification by the RIRs is prone
to sadness. My initial intent was merely to state that I prefer the RIRs not waste additional
resources on this, including notification.
