In reply to Anthony Burchell.

I don´t disagree with anythingin your comment but headless WP is generally defined as pluginless with a javascript front end.

I think this is flawed, server rendering the markup (html or it successors) is the future. With improving bandwidth, server speeds, service workers, smart caching etc the trends are wordking against javascript front ends, the cool kids are not so smart ;-)

And for server rendered markup the traditional wordpress plus plugin architecture is perfect. Even if wordpress itself could do with some backend improvements to handle new types of data and experiences.
