I might argue that the 3 PTO suggestion for the issuer makes sense. We need some guidance for the issuer that is easy to implement and also tolerant to reordering. 3 PTO is a good fit for that.

The question IMO is if we need something more than that. It might be possible to argue that the current recommendation of 1 PTO is a rough derivation of the 3 PTO rule, but it's confusing.

Maybe something like "SHOULD ... in a timely manner, as the issuer of the CIDs might drop the retired CIDs as early as 3 PTO" would be enough.
