 > I've found the reason why. While the documentation page and the
 Gutenberg plugin are using the Widget's class `$show_instance_in_rest`
 property. WordPress decided to stop checking this property into the
 Widgets REST endpoints in favor of looking into the
 `$widget_options['show_instance_in_rest']` property.

 @imath thanks for chasing down and identifying the problem.

 > If you think it's not needed, I'd advise to at least update this
 [https://developer.wordpress.org/block-editor/how-to-guides/widgets
 /legacy-widget-block/ documentation page] (to avoid misleading developers)
 to explain people now need to include a
 `$widget_options['show_instance_in_rest'] = true` when registering their
 widget.

 The docs do need to be updated, which can be done upstream in the
 Gutenberg repo.

 What about the patch?

 As this is a new feature that hasn't shipped yet, I'm concerned about
 adding code. Why? The added code has to be maintained in core and could
 confuse both extenders and contributors.
