Agenda+ Change Proposals – progress and review

Change Proposal 12 [5] has not been updated but Glenn has made changes that address many of the issues in there [6].
Can we agree to set the default @validationAction to "warn" and make it a recommendation to the validator rather than mandatory?

Change Proposal 2 [4] has been implemented and has been pending review for over 1 month
Can we mark as CLOSED – IMPLEMENTED?

Change Proposal Index is at [3].
Which Change Proposals would owners like to progress next? There are 20 open CPs.
