Thanks for asking for this capability. This isn’t in our current plans. We suggest using the Group Calendar functionality for great Microsoft Exchange backed features like recurring events.

The Group Calendar is (sadly) not a possible solution for our Intranet. Modern Communication sites do not include a Group Calendar, and for Modern Team sites, the Group Calendar does not have a viewer security role. We would actually LOVE to use a real Outlook Group or Shared calendar rather than a SharePoint list calendar IF the Outlook calendar could be visible to site visitors and not just Members/Owners.
