In reply to The Answer Guy.

I find myself disagreeing with this 'headless' view. WordPress has become an application, as opposed to just a blog platform (long since moved on from) and a CMS. It is bloated with legacy features and code. As I understand it, and I could easily be wrong, plugins and themes can be used with the REST API. Certainly, the demo I saw yesterday did just that. The back end does not change, and it is that part of WordPress that is most useful.

Now we see lots of basic themes and a spreading array of specialist themes. I use a theme framework, Ultimatum Theme, that already de-couples much of the WordPress front end. They are chomping at the bit to be able to use a fully fledged REST API, to be able to remove the last vestiges of the WordPress front end. The REST API allows developers to make customer centric solutions for both desktop and mobile, where integration and flexibility is the key.

As a developer, it is frustrating to spend 90% of the project development time on finessing WordPress Themes, Plugins and HTML/CSS/PHP/JS code. As it is, I hope that WP REST API V2 will appear as 'stable' within 3 months, but I know that it will not progress into core until at least WP4.4 (December 2015?).
