In reply to Miroslav Glavic.

Miroslav - I've also been around long enough to see the push back you are describing on all kinds of change. The Customizer was a great example.

But it's worth emphasizing in this case:
* While there is some general push back on Gutenberg as a whole, much of the push back is NOT about rejecting Gutenberg. It's just about the timing and release management.
* Gutenberg is a huge update that changes the core interface of WP and has major backwards compatibility concerns for the whole ecosystem. It's ultimately a good change. But if you push something like that before it's ready in an ecosystem as complex as WordPress, it will be a disaster.
* This same push back over timing is also coming from a lot of very committed, long time WP veterans who carry a lot of weight in the community. It's not just the usual outsiders rejecting change.

I think most people just want to slow down, not rush the release, and do it right.

Gutenberg needs to get to stable first (and its not there yet), and only then give the ecosystem a solid chunk of time to adapt.
