Comment (by danielbachhuber):

 > What else would that kind of specification entail? Turning off parts of
 core UI? Explicit checks before assigning the post_parent?

 This is certainly something that needs to be fleshed out. At the very
 least, it could be an informational flag for WP-API — `post_type_supports(
 'attachment' )`. However, it's worthwhile to do some technical discovery
 on whether such a flag should have an impact on existing components and UI
 in WordPress.

 I'm open to suggestions on how we could make the inference that a post
 type supports attachments if we want to punt on adding something to core,
 but I don't have any great ideas at the moment.
