Currently, an event's RSVP list is only visible to a single admin, and that person also has full access to edit the RSVP page. A way to make the list available to multiple admins, some of whom may not have edit-access, would be very helpful.

One way to do it would be to add support for storing the list as a Google Sheets document, rather than an internal format that can only be exported to the Excel format (and only on-demand by the sole admin).
