Why must they discard any topology? They might have problems to charge
for /48 instead of /64 if /48 becomes "usual" at the competitors, yeah.
But that's primarily a business thing.

Hm? I guess you are referring to cable modem stuff?

Over here (DE), almost all residential users use dial-up, be it real
(analog, ISDN) or virtual (DSL, via PPPoE). So they are connected via
virtual interfaces, and get their IP address usually via dynamic pools
or static via RADIUS. No problem adapting this to assign /48s
(especially via RADIUS).

And then charged additional install and monthly fee? Cool. We want to
get rid of this as much as possible. Artificial scarcity sucks. In IPv4,
there is the perceived scarcity excuse for ISPs. Don't recreate that in
IPv6, thanks.

The mantra is "/48, no questions asked, and by default".

So what? If done properly, someone who doesn't care can just ignore
the availability of the rest.

But as someone else noticed, this discussion is sliding off.
