In other words, a mesh of standard Ethernet bridges already
allows you to partition traffic between the segments, without
the need to do configuration of routers. (Yes, you do have to
arrange the connectivity so that voice traffic doesn't have
to go over the HD video network to get to the site exit
router, but that's true whether the devices in question are bridges or
routers.)
And if that's true, then a /64 would be fine for the average
home user. Am I missing something?
The IETF designs protocols, it does not specify what products people
MUST buy. Many home users currently buy IPv4 routers, not bridges, and
there is no reason to believe that this will change with IPv6. In
addition, a lot of home users set up Linux/BSD/Windows to act as routers
in their home network.
The reason for a /48 everywhere is so that nobody needs to dig into such
dirty details and fine tune who gets how many addresses in which
situation.
