To put it a bit differently, changing the security considerations for RFC3046 is out of scope for this document. It could certainly be argued that the security considerations for RFC3046 are too weak, but if that is an argument that someone wants to make, the argument should be made in the context of updating RFC3046, not in the context of adding a new DHCP relay option.
