You appear to be focused on number of devices. Think different media types. There is no reason that any new media type should be stuck with 25 year old framing technology. We get there by default now because multi-media bridging is known to be broken and to date routing has been too hard. There is nothing really magic about local routing though so it is reasonable to conclude that over the 500+ year lifetime we expect for IPv6 that differing media types will arrive with framing that is better routed than bridged, and that trivial management of local routing for structured topologies will appear.
