If you have a 6to4 gateway, you should advertise 2002::/16 so that your
network will know how to find the gateway and thus reach 6to4 nodes.
If you are *using* 6to4 addresses, then once you have formed your /48
prefix, you may well be subnetting that, and you likely want to advertise
/64s (or however you subnet) internal to your network.

I'm not entirely clear why an ISP that had, for instance 18.104.22.168/19,
couldn't advertise a gateway to 2002:d197:0000::/35 to its v6 peers.
