Good read. Some form of hop-limit seems sensible to me.
While favoring routes through higher-cap nodes seems like a good idea, their analysis seems to assume all honest nodes (n) support OM relay to all peers. I’m concerned with the incentive to serve as a relay to non-channel peers.
Given this is related to the recently merged option_onion_messages_only_channels, I’m curious if anyone has data regarding how many nodes support `option_onion_messages` and how this has been trending over time? And I’m interested in how that number compares to option_onion_messages_only_channels moving forward.
