Fortunately 2002::/16 orlonger is pretty well filtered.
You are saying that if an ISP gets a /32 from a RIR it is no problem, but a 2002::xxyy/32 suddenly is a problem?
Yes, because 2002::xxyy/32 or whatever, as a direct import of the IPv4 routes results in much more routing table explosion than an ISP getting a /32.
The ISP that I used to work for is relatively small and has to inject 7 IPv4 routes into the DFZ. When they go with IPv6 (alas, they haven't started that work yet, to my knowledge...I keep poking, though), they'll have 1 that will provide them with IPv6 space for pretty much any anticipated needs long long into the future.
