On the receiving end, the outdated values are discarded, and they will only waste bandwidth: https://github.com/solana-labs/solana/blob/3f0480d06/core/src/crds_gossip_pull.rs#L385-L400 This is also exacerbating validator start, since the entrypoint is returning old values in pull responses, and the validator immediately discards those; resulting in huge delay until the validator obtains contact-info of the entrypoint and is able to adopt shred-version and fully start.
