It's quite clear that Mullenweg is not listening to any of the concerns raised by the wider WordPress community, instead all he's interested in is obsessing with his PR campaign. Developers and users want clarity about dates because they need to make contingency arrangements. Surely Mullenweg doesn't expect users to have people hanging around indefinitely on the off chance that at some vague point between now and the end of January he declares Gutenberg to be fit for purpose. It's a shameful way to treat the thousands who have remained loyal to WP over the years and have helped to make it the huge player it is now.
