That's great that you checked Chris, and I don't mean to be to overly
dismissive, but that's not how the CA/Browser Forum Baseline Requirements
are written, nor how it's operated.
It's a technical specification, and one every CA is obligated to state
compliance to the latest published version (which has undergone both voting
and IP review). You will be violating your CP/CPS if you attempt this
retroactive correction, and should receive a qualified audit because of it,
independent of Ballot 194, because of this.

This is not true. There is still the IPR review.

This is misstating the agreed upon process for ballots. Until it's
completed the IP Review, it's not adopted.

That's not something the Forum members can or should be stating.

This suggests that CAs are poorly designing their software and/or poorly
staffing engineering. I suspect both.

I'm sorry, but it has yet to be demonstrated how this can be true. Nothing
requires all of this information be revalidated on a single day. On April
22, when it comes into effect, you only need to revalidate new
certificates. This is no different than if you were to acquire a new
customer on April 22. There is nothing in Ballot 193 that requires a full
re-validation as you've described.

As proposed, it's a negative for security. Let's focus on making real
