We did have this discussion at the face-to-face, and I'm fairly sure you
were present, as it was with the whole room. It's somewhat frustrating
that this is not yet reflected in the minutes. But perhaps you can rack
your memory? :-)

As noted at the time, the audit situation needs fixing, but fixing it is
difficult and will be time-consuming. Domain validation is an important
enough CA function that we feel it should be done in-house in all cases,
and taken out of the audit quagmire with a simple ban. No CA came
forward at the face-to-face to say this would be a problem for them.
