What requirements do you have that are fundamentally incompatible
with using multiple addresses?

How would a default-free content provider with 1000+  peering sessions
be handled?  Would they be treated as an ISP, even though they have no
downstreams, and get PI space?
There are a few corner cases that fall through the cracks in today's policies. A content network like you describe would be one, a transit ISP with customers that all have their own addresses would be another: where would they get the IPv6 addresses to number their routers?

However, the number of such networks is so incredibly small that whatever happens to them is completely insignificant with regard to scalability. Still, we need a decent policy for these cases, and JUST these cases but not random people who'd also like a /32.

Or would you expect them to get prefixes from every peer they have, and configure several hundred IP addresses on each server?
Getting address space from a peer doesn't make much sense. But 99.999% of all content networks have 1 or more ISPs that they can get address space from and then announce to any peers.

I'll be blunt. As long as that question is up in the air, none of the major content providers are going to do anything serious in the IPv6 arena.
Well, I have no evidence of them doing anything with IPv6 anyway, so I don't know if this makes a difference.

The whole point of IPv6 is that we have a technology that will allow our networks to grow for decades to come. Importing IPv4 mistakes defeats the purpose.

ACLs are already enough of a hassle with one
IP address per host.
Ok, let's see... which is more important to keep the internet running, a routing table that fits in our routers, or acl monkeys that get to go home at 5?
