I support working on leaderless election.
I’m a bit confused, because I don’t think that’s really the question at issue. The first question was whether leaderless election (other than ubiquitous configuration) can even work, given arbitrary algorithms. Computing a flooding topology is a global problem. The decisions made for one link may affect how flooding should act on another link on the other side of the network. How do you make a global decision without global information? The second question was whether such an election should be decoupled from the existing distoptflood draft. I think so, as we want it to span algorithms.
