Message:

Posts, Post Types: Autosave: Allow disabling autosave support per post type.

Not all post types support autosaving. By making autosave a post type feature, support can be more granularly handled without any workarounds or hardcoded allowlists. wp_font_family and wp_font_face are examples of built-in post types which do not support autosave.

For backward compatibility reasons, adding editor support implies autosave support, so one would need to explicitly use remove_post_type_support() to remove it again.

Props swissspidy, youknowriad, hellofromtonya, peterwilsoncc.
Fixes #41172.
