As a general rule you don't grant exceptions, and so exceptions are
let's say, an exception to that general rule? Hence the name.

So, to the same end as my original proposal, I recommend instead that
Mozilla personalizes any CA survey sent out to a CA which they believe
currently benefits from any such exceptions - setting out what those
exceptions to its rules are for that CA. And in all communications the
text should be clear that any exceptions the CA believed were in place
are in fact spent as far as Mozilla is concerned unless they are
enumerated in this communication.

In the event there are in fact NO exceptions, that's just one small
tweak to the text.

In the event that one or two CAs benefit from some minor exception
which still has force, it's a little bit of work, and in the process a
firm reminder to both Mozilla and the CA of the ongoing price of such
exceptions.

And in the event that it's actually dozens of exceptions across many or
most CAs I hope the realisation of the effort involved will cause Wayne
to reconsider his previous claim that "as a general rule, we don't".

One valuable opportunity from m.d.s.policy is for CAs to learn from
each others mistakes and in doing so avoid making the same or similar
mistakes themselves. But Mozilla has opportunities to learn from
mistakes here too, and I feel as though the mismatch between Kathleen's
expectation (that a situation should have "resolved" since 2016) and
the CA's understanding (that this constituted an indefinite exception
to Mozilla policy) is such a mistake.


Nick.
