You are absolutely right that Gutenberg can improve accessibility concerning content, however this is not a reality yet. People are concerned that, on the day Gutenberg goes live in less than 3 weeks, accessibility will be worse than what it is now. So the issue here is not about releasing Gutenberg or not, but to release it as the default experience on a later date, once all these accessibility potentials become realities...
