Does Gutenberg affect all CPTs?

Hi

You can find limited answer to your question here https://www.ads-software.com/gutenberg/handbook/reference/faq/#will-custom-post-types-be-supported

Furthermore, for a custom post type to support Gutenberg, and have the interface show up, you’ll need to enable that post type in the rest api using show_in_rest: true https://codex.www.ads-software.com/Function_Reference/register_post_type

The same goes for taxonomies.

oh well that just created two more questions, lol:
1. What kind of content input field will CPT that dont support Gutenberg have? The standard Wysiwyg field?
2. Gutenberg support for CPTs is tied to REST? They aren’t the same thing so why?
