"The prompt invites users to install Gutenberg if they want to try the new editor or install the Classic Editor to keep using the current editor until they are ready to make the change."

What about the people who will never be ready to make that change and don't want to hear anything about Gutenberg, ever?

- Clicking on "dismiss" will keep things as they are without any further notification or this will simply dismiss the notice and install Gutenberg at next update without further approval?
