I recommend that the address block be published in the document when it becomes an RFC. It's also arguable that 6to4 implementations should recognize addresses from the assigned prefix and disable 6to4 when configured with such addresses. The document could perhaps make it clearer that this prefix is intended for assignment by access providers and not, e.g., by enterprise networks or for use in interconnection between private networks.
