Right, that is why from Gutenberg initially being “just for post edit” now is in the widgets area, in the Customiser, FSE, everywhere basically?
Because it will “never going to take over”? I would say, it already took over.

Hanging on “just disable it” will not resolve the problem on the long term. It is a short term solution. If you do not like Gutenberg, now in 2022 that is equivalent to say no to WordPress itself.
It’s not that Gutenberg is going anywhere away from it. It will not be removed, believe me on that. It will only be pushed more and more.
