Right. And this is in fact implied by the current text: "the 6rd Tunnel MTU should be set to the known IPv4 MTU minus the size of the encapsulating IPv4 header (20 bytes)" Since ISPs know in general that they support IPv4 MTUs well beyond 1300, they should tunnel MTUs to well beyond 1280. It is only "Absent of more specific information" that "the 6rd Tunnel MTU SHOULD default to 1280 bytes."
