Sorry to be late to this, the goals seem great. The question that comes to my mind is will the current 1.x line will be maintained?
That may be a parallel issue to the goals, but it is important if we are dropping support for Java versions. I would think that *some* position on that has to be decided and communicated ( if not voted on ).

There appears to be general agreement on the path forward, so I will initiate a vote thread soon. I'm sure there are additional details to be worked out, and we can address those following a vote on the general goals.
