Right.  And we need to make sure ISPs and vendors are able to provide Joe
with the option(s) he wants.

IMHO, dynamic assignment is the default now primarily because it's the
easiest model to support.  Just tell the user to plug in their PC (or
whatever) and it works -- no messing with complicated IP settings.  The
problem comes when providers lock things down so that a given user can only
get one DHCP address or use one MAC at a time; mine happens not to do that
(though multiple hosts are against the AUP), but I suspect there are many
that do.

Banning servers is handled more easily through AUP enforcement than via the
addressing model.  Sure, it requires a bit more work to run a server on a
dynamic address, but it's still possible and still an AUP violation for most
consumer accounts.  Providing insufficient upstream bandwidth is the most
effective method in any case.

Then I think it's up to the IPng WG, perhaps at the RIRs' request, to come
up with standards for how we expect such devices to work with IPv6.

Vendors do generally try to do the right thing given the constraints of the
market dynamics they face.  Telling them "every home must get a /48" or even
a /64 will end up just as futile as saying "don't do NAT" was.  The market
disagreed with the IETF, and the market always wins.
