TC39 provides a venue where I would hope we can do exactly this sort of work. In addition to actually creating new editions of the standard, there's no reason we can't create and public roadmaps, deprecation plans, specifications for common extensions that are candidates for inclusion in future editions, recommendations for implementers, or whatever we think will be helpful in evolving the language in a way that will maximize interoperability. The main thing necessary for this to happen is a agreement among the members and a commitment from them (us...) to do the work to get it done.
