+1 RE: Merge 208 and/or 702 as they're ready - so zeppelin can benefit from the merits of both approaches. That’s been my understanding as well, as discussed in this [1] thread.
+1 on Tom’s comments as well. Hoping for no more arguing in this dev list - so we can get back to our regularly scheduled positive ASF contribution spirit.
