Tighten restriction on a "seen" attestation
...
Declares that only a verified block can stop an attestation from being propagated.
This achieves two things:
1. Ensures that clients don't need to scan invalid blocks for attestations and then modify their state based upon them.
1. Disallows "muting" attestations by sending around a junk block with that attestation in it.

There is no need to mention clock disparity when comparing two static slot values (assuming the clock disparity is less than a slot, even then I don't think that's the intention).

Add fork version to topic
...
Gossipsub peers are separate from the ETH2 RPC protocol, and thus cannot
rely on the application-level `Status` negotiation to establish if
they're on the same network.
Segregating gossipsub topics by fork version decouples RPC from gossip
further and allows peers to more easily listen only to the traffic of
the network they're interested in, without further negotiation.

drop `head_block_root` from BeaconBlocksByRange
...
This change simplifies the protocol and removes a race condition between
block request and response. In the case of honest server, this helps
serve the canonical / fork-chosen chain better while dishonest or broken
servers still need to be handled the same way.
Might as well get started on versions and upgrade it to 2, since the
change is backwards incompatible.
