Of course, if implementors choose to drop the code you might not be

Which is exactly why HISTORIC is NOT appropriate.
With rfc3484-revise and the documented brokenness of 6to4, it doesn't make
any sense for implementors to offer 6to4 anyhow. So I think it would be
quite weird to keep 6to4 at standards track just to prevent some vendors from
dropping 6to4 support.
