Comment:

 [attachment:37667.diff] is a patch for what the implementation of this
 proposal could look like.

 All features are stored in a private `$features` property in
 `WP_Post_Type`. The related methods explicitly handle subtypes (like we
 have for attachments with `attachment:audio` and `attachment:video`) - for
 example, calling `$attachment_post_type->supports( 'thumbnail', 'audio' )`
 would be the same as calling `post_type_supports( 'attachment:audio',
 'thumbnail' )`.

 There's a method `remove_supports()` in `WP_Post_Type` which might not be
 necessary any longer after this change. It could be left as is or
 deprecated.
