In reply to Mike Schinkel.

Agreed. WordPress needs to continue with releases on the scheduled we are accustomed too: 1, 2 or 3 major releases each year. I have no idea why anyone from WP core dev team has mentioned 5.0 as the target, but it was a bad decision on their part.

What if Gutenberg needs one more year to be near completion - we will not see another major WP after 4.9 until 2019? That is completely insane. There are plenty of things that need to be implemented, and Gutenberg is not the priority core devs make it be considering everything, especially the React issue.

React can't be included in the core, for as long as it is licensed the way it is. There are alternatives like Preact that would be easier to rewrite for, all complete rewrite to Vue. But, that should be started before it is too late. And, as with any JavaScript in WordPress, Gutenberg is very badly documented, and the more it grows, the time needed for rewrite will grow exponentially.

These and many more important issues raised in these comments need to be answered and resolved as soon as possible, and Matt (or any one else from core dev team) has not really responded to big questions included React license, Gutenberg schedule, severe lack of documentation, future WP releases until Gutenberg is ready, meta boxes and all the current actions and filters related to post saving.

Gutenberg development should be paused until all these issues are addressed and clear development path is created to keep the backwards compatibility, remove React and unburden WordPress releases from waiting on Gutenberg.
