Can this feature be added? Having any type of calendar that cannot also be accessed via the ical format in 2024 seems almost archaic at this point. Ripping out the events page and adding a calendar widget is also not a suitable compromise, because of the deep integration with other features in the site.
One should be able to have all the nice things about the events page and allow people to subscribe to a .ics subscription to receive the same information in their calendar apps.
