During the last months, we participated in testing Gutenberg with our plugins - WPML and Toolset. We found bugs in GB, created tickets and MRs, but they're being overlooked. We are getting very slow and strict replies to our fix requests, while the project runs forward, ignoring many problems.

Then, we're going to get slapped on the hand because our plugins have "compatibility problems" with Gutenberg. That's really great, encouraging, inclusive and democratic.
