Background: We want to update the permissions for the organizer side of Event Registration so that it is available for all autoconfirmed users. We also want wikis to be able to let us know is they want to keep the status quo instead (i.e., only available to users with the event organizer right). This should only be released after a period of community outreach and consultation to inform communities, so that wikis have time to let us know if they want to opt out of the change.
