You are suggesting to assign a new IP prefix every time, some implemtations
out there fucked up?

If you can't live with anycast, go and announce our unicast more specific!

No, they don't otherwise firewalls would not work with IPv6 and 6to4 at all.
Any nativly IPv6 connected host respond to any request from IPv6 addresses
using IPv6.

I see you point, that more specifics of 2002::/16 are disallowed by RFC3056,
but this can easily be changed. 6rd uses the same way to modify RFC3056: It
requires a huge parallel prefix (and route) per ISP.

In order to overcome the situation I submitted a draft to the IETF.

Have fun.
