Support for providing a public key hash in peer lists

[xloem]

Would it be possible to upgrade the protocol so that peers can be associated with a public key hash, so that their identity could be verified if they support TLS communication?

This would help prevent censorship.

I spent some time working with cosmos family blockchains, and in their protocol this is already done. Each peer connection is encrypted and gossips the public keys of its neighbors.

I mention this because I recently encountered this issue regarding ar-io's gateway system, posted in discord (scroll right to see cert errors):
