Pinging on this patch as well.  If we want the notmuch2 python module to
be used, we need to get it in wider distribution.  having it installable
via "apt install python3-notmuch2" would be a good start.

Note that making this change means that the notmuch package will pass
through the NEW queue, which can take longer than we might like,
depending on the Debian FTP team's available time.  I see this as an
argument for making this change earlier, rather than later, though, so
that the NEW queue doesn't trip us up if we have a more urgent change we
want to see made later.
