Does TaskWarrior support CalDAV ? I use todoman, it is a CalDAV-based todo manager. Todos are read from individual icsfiles from the configured directory. This matches the vdirspecification.

It is part of pimutils project [ https://pimutils.org ]
vdirsyncer can be used to sync with CalDAV server such as Nextcloud.
