From what I understand of this recap is that Automattic has already decided the future and the non-Automatticians can just disconnect their keyboards and go home and not waste any time in more meetings. Were there any non-Automatticians in the meeting at all? Not based on the quotes except for the last one about themes not going anywhere by Ari Stathopoulos.

Gutenberg Automattic team has decided and that's it. No matter that the whole block based theme system is bonkers, who cares, Gutenberg storage method was bonkers from the get go and now the Core team will expand the bonkering to other places of WordPress.
