To me there is none; never has been. BCH didn't have to be a hardfork, that was just egos overestimating their own importance. But in today's environment some people have a hardon for hardforking. Some even write BIPs, to confiscate coin or to confiscate jpegs. It will always be contentious.

No matter which camp forks first, it would be good to have a set of tested methods to maintain channels in the face of adversity, no matter who the fork originates from. We know that channels are vulnerable because you have an ongoing relation with a counterparty, not just a single event like paying someone straight.

We need to understand how to deal with it, before a hardfork happens, so that we can be properly prepared. We're already late in the game and I was hoping there was just some repo out there with someone gaming this out in a set of reproducable scripts. But if there is none, then it shall be made.
