Baseline requirements are not an imaginary problem. All of them have a legitimate reason for existing. You could argue that some "are not that big of a deal", but that's exactly the point, the overbearing and overly specific requirements serve both their own purpose and double as Van Halen's "no brown M&Ms" clause: if the CA screws them up, either by malice or incompetence and doesn't immediately catch them and self-report, then you know they have no way of telling what other things they are screwing up. And if you're in the business of selling trust, that instantly makes you untrustworthy.

There are countless Bugzilla reports of clearly unprofessional CAs trying to get away with doing whatever they want, get caught, say "it's no big deal", fail to learn the lesson and eventually get kicked out, much to the chagrin and bewilderment of their management, irate that some nerds on the Internet could ruin their business, failing to understand that following the scripture of the Internet nerds is the #1 requirement of the business they chose to run.

Yes. Brown M&M tests are exactly what's called for here. You want a strong psychological urge to obey rules just because they're rules. There are roles where this isn't the right thing, but operating a Certificate Authority isn't one of them.

In my experience every case in the Web PKI where we found what seems obviously to be either gross incompetence or outright criminality there were also widespread technical failures at the same CA. Principles who aren't obeying the most important rules also invariably don't care about merely technical violations, which are easier to identify.

For example, CrossCert had numerous technical problems to go along with the fact that obviously nobody involved was obeying important rules. I remember at one point asking, so, this paperwork says you issue only for (South) Korea, but, these certs are explicitly not for Korea, so, what technical measure was in place to ensure you didn't issue them and why did it fail? And obviously the answer is they didn't give a shit, they'd probably never read that paperwork after submitting it, they were just assuming it doesn't matter...
