Additionally, forkid validation via the discovery protocol requires ENR implementation (EIP-778) and ENR extension support (EIP-868), which is not mandated by the Ethereum network currently. Lastly, the discovery protocol is just one way to find peers, but systems that cannot use UDP or that rely on other mechanism (e.g. DNS discovery (EIP-1459)) still need a way to filter connections.

EIP-1459 is still in review, not final, which means it is blocking this from being merged. Since it is just used as an example, can we just remove it?

@timbeiko Can you review/approve again? The reference to EIP-1459 was removed and I would like to get author sign-off on that change before approving.
