In my considered opinion as FTSC member, former FTSC chair person, co-author of FTS-5000.005 and your dedicated nodelist clerck: yes!
HD> The U,MOB flag does not cut wood, as we donot know how to connect it. HD> I.e that systems are operating like a Point.
Ironically the U.MOB flag /does/ provide some information. It used to be different five years ago but these days in most Western European countries mobile devices do not get a publically routable IP address. AFAIK only some Scndinavian mobile operators hand out IPv6 addresses. IPv4 is behind CGNAT.
So most of these U,MOB nodes are not nodes who's contact information is known to their uplink, but not made available to all. There just is no such information. Period. They are not connectable. Not by the general public and not by insiders. They get their mail by polling their uplink.
This may change in future, but as it is now, these U,MOB nodes have the contactability of a point. Pretending that they are fully fledged nodes is politics.
