AFAICT, there are no semantic issues raised by these changes. Is there any urgency I'm missing (like an impending 7.x Nightly) for resolving these concrete syntactic and naming issues sooner rather than later? 

No, no rush -- just wanted to let es-discuss know about the update so we can have plenty of discussion time.
