In reply to Fabio.

I think this has a lot of potential for a bit further down the road, and I wouldn't just restrict it to Automattic.

Three or four years ago, there was very little modern JavaScript development happening in the WordPress world. Over that time, modern JavaScript has been embraced by a bunch of different companies. Product companies like Automattic and Yoast are building all their new things with modern JavaScript, agencies like Human Made and 10up are building all their client sites with modern JavaScript. Over a very short time, the WordPress world has amassed a huge amount of world class JavaScript knowledge and experience.

The next phase of that is to distill that knowledge back into Core. Take all of the component libraries, workflows, and patterns; and bring them together in a way that gives the entire WordPress world - regardless of whether they've managed to find the time to Learn JavaScript Deeply - the opportunity to join in the fun.

Back to your original question, maybe that will involve creating an "official" WordPress framework, maybe not. Having projects working independently of the major players is an important part of how the wider JavaScript ecosystem evolves, I think WordPress can fit into that ecosystem without needing to build our own thing, or take an existing thing and make it our own.
