Oh, no, that wont work. Some configuration steps for the tap will not happen in this case -- one of the ioctls (TUN or POINT_TO_POINT) needs to happen. See the two-line diff I had sent earlier. So that explains why the tunnel doesn't work when no v4 address is set. While we do need to do further tests to ensure setting tap for TUN mode using 0/0/0 doesn't break anything, skipping it is not an option.
