In reply to GJ.

I have to agree a bit.

While I understand this showcases what can be done with REST API, and is a great launching point for people building custom interfaces into WordPress (important, for sure)... I'm frustrated to see this kind of work prioritized over other stuff that would seem to be more basic. For example, a better comment system. Or putting more resources into bbPress/BuddyPress. Or (from a post or two back) making a better repository to make life easier for developers.
