This is why I support Natalya's first option, in particular regard to Abtract and Collectonian;The parties may not edit, at all, any page that the other party has been involved in editing recently...with perhaps 50 edits/two weeks being the definition. It stops them coming into contact. If Abtract and Sesshomaru want to work informally to Abtracts formula (and Collectonian notes Abtracts areas of interests), then it simply means they don't report each other. The original restriction remains, with Natalya's new wording, so that any future disagreement can be resolved back to those principles (it may avoid a party trying to redefine what the informal agreement means). Also, I don't see any reason for a time limit - if it works it stays. As regards being thin skinned (or not) I might not have looked recently but I'm pretty sure this is the encyclopedia that anyone can edit, and not those with particular epidermis qualities. I think this is what we are aiming for.

As regards bringing this to a wider review, I think there have been various postings to the admin boards in the past and what we are doing here is the result of that; I don't see what taking it back yet again will achieve. If we can't sort it here, then I think we are left with WP:RfAR - since this is exactly what that body was created for.
