Addendum: I think the key variable here is how much cheaper and easier the mechanism makes coordination relative to the actual cost that gets people with soft preferences to participate.
It feels like because the groups that are already working to drive inadequate equilibria are already investing in coordination mechanisms, making coordination cheaper and easier will be a net-loss until the soft preference threshold is crossed.
