 > The hook `remove_theme_support( 'widgets-block-editor' )` only removes
 Widget Block Editor. Does it not do that?

 No, it doesn't do that in my testing.

 > Because the documentation appears to indicate we need to install the
 Classic Widgets Editor plugin separately to restore the class widgets
 editor.

 I believe this is not true though. The documentation indicates that one of
 the three methods mentioned should work independently.

 Testing instructions:

 1. Add `remove_theme_support( 'widgets-block-editor' )` to a theme in a
 `after_setup_theme` action.
 2. Go to Appearance -> Widgets.
 3. Should see the classic widgets editor rather than the widgets block
 editor.

 > I have also tried using add_filter(
 'gutenberg_use_widgets_block_editor', '__return_false' ); according to the
 instructions here: https://developer.wordpress.org/block-editor/how-to-
 guides/widgets/opting-out/ but that doesn't work either.

 This doesn't work for me either. I believe this is a bug in the
 documentation. We need to update the filter to be `add_filter(
 'use_widgets_block_editor', '__return_false' );` instead, which works for
 me.
