Onion Messaging DoS Threat Mitigations

The concept of implementing a hop-limit to prioritize routes through nodes with higher capacities appears to be a promising strategy for enhancing network efficiency. This idea is predicated on the assumption that all honest nodes are supportive of Onion Messaging (OM) relay to every peer, which raises some concerns about the incentives for nodes to relay messages to non-channel peers. The intricacies of these relationships between nodes and their willingness to act as relays without direct channel connections require further exploration.

Recent developments have seen the integration of the option_onion_messages_only_channels into wider network protocols, marking a pivotal shift in how node communications could be structured moving forward. This change brings to light the need for comprehensive data on the adoption and support of the option_onion_messages feature across various nodes. Understanding the trends in node support for this feature compared to the newly merged option_onion_messages_only_channels will provide valuable insights into the evolving landscape of node behavior and network functionality.
