Future of Caledar with SabreDAV maintenance on hold?

Just wondering what the plan is regarding the Calendar (and contacts?) appā€¦ and I guess WebDAV in general, since the server side back-end SabreDAV seems to have lost its main maintainer:

Doesnā€™t really explain much, but I noticed that some of the contributors to Nextcloud have also been active in the sabredav repository latelyā€¦ so I guess they are doing a bit of maintenance for now :slight_smile:

Iā€™m also worried too.

Iā€™d love to see some new mainteners on Sabre/Dav

arent calendar, contacts and webdav ā€˜featuredā€™ in NC 12+ ? meaningā€¦ NC-devs would (hopefully) take care of a working solution
