No, but don't you think it might be a hindrance to getting the dispute resolved? Which precise problem are we trying to solve here?
A mailing list need not have a specific goal (and indeed it rarely does); rather, it is simply a forum for discussion of a given topic - which is often quite loosely defined. Consider this: which problem is WikiEN-l trying to solve? It's not; the list exists simply as a place for collaboration and discussion that would not be handled as well on-wiki. As a rule of thumb, I prefer on-wiki discussions for consensus-building, but I *do* think this list is a good idea - if for no other reason but to see how well it works.
On another note: to safeguard against having this list sit uselessly if we end up discovering we don't want to use it, we could agree to consider in, say, three months whether the list ought to be closed down or not. We already have quite enough lists that are barely (or not) used.
