"Luke Dashjr's pattern-based filtering in Bitcoin Knots creates a cat-and-mouse game that worsens mining centralization: when nodes filter inscription transactions, users may attempt to bypass the P2P full-node network entirely, establishing private relay networks directly to mining farms." Side channels do not "increase mining centralization" at all. If people mining have filters, regardless of if it is relayed via gossip or side channel makes no difference to mining power. In fact Datum and StratumV2 increase decentralization while including transaction choice. So the abstract itself is flawed. "Meanwhile, Bitcoin Core's proposal to uncap the OP_RETURN limit in Core30 may create severe legal vulnerabilities for node operators who would be forced to download and store arbitrary data that could contain illegal content." This is not the threat, tripping Malware detection and antivirus software is the threat. This would likely shutdown cloud run nodes (like those hosted on Cloudflare, or AWS) it has nothing to do with legality. Rewrite the abstract or I don't care to read the rest of the proposal.
