cc @Udehb-WMF, heads up about a new potential power/ability available to those with the event organizer right

Notes:
Technically, CC doesn't yet support this.
Socially, we might want to consider if this is really necessary and if it really aligns with why this Event organizer right was created. There might also be trust / safety concerns about a change like this.

We won't be working on this in the near-term. Long term, we may want to reconsider or decline this task.

One note on Trust & Safety concerns, @KStoller-WMF: One of the values of the Event Organizer right is that it is relatively simple and straight-forward for organizers to get the right, since they can only modify their own event pages (rather than having privileges beyond that). This makes the right pretty low-risk in terms of T&S concerns. This proposed change would give them more powers, since they could moderate and curate promotional content that has a lot of eyeballs on it. However, one thing that we have discussed in the Campaigns team is to perhaps eventually create a 'super organizer' right, which could perhaps also be managed by wiki admins, but it gives that smaller group of organizers more privileges. We haven't found a good use case for it yet, so we haven't looked into it, but if there is interest in working on this later (as I understand it's not a near-term project for the team), we can certainly chat about this option and see if it makes sense.
