Bug#866795: gnome-contacts: No CardDAV support?

[Conrad J.C. Hughes (for Debian package stuff)]

Package: gnome-contacts
Version: 3.22.1-1+b2
Severity: important

Dear Maintainer,

[I suspect this is closely related to my encountering a similar problem wrt
CalDAV calendars, submitted as bug #866794 versus gnome-calendar; please mark
as duplicate/move to gnome-online-accounts if that's where this should really
reside]

I've just upgraded from jessie to stretch, and now cannot find a means of
adding my CardDAV server as a source of contacts: there's a huge list of
options, but nothing that seems to support CardDAV, which I used successfully
on jessie.

Currently the only way to add an address book seems to be to add an account,
but the list of account types doesn't seem to include anything that would
permit use of a CardDAV URL.  I can't see any mention of DAV in the release
notes either for this or for stretch itself.

Any suggestions please?

Regards,
Conrad
