- timestamp-based filtering of `channel_update` messages: only ask for `channel_update` messages that are newer than the ones you already have.
- checksum-based filtering of `channel_update` messages: only ask for `channel_update` messages that carry different information from the ones you already have.
Nodes can signal that they support extended gossip queries with the `gossip_queries_ex` feature bit.
