I would be happy if I knew about deployments being cooked that
required /64 per user, let alone anything more. I still have a hard
time imagining what technology will deployed at most sites that
_require_ separate subnets, but I am trying to be generous and will
accept that a few might be needed.
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.
