RFC-37: Embeds as a New Confluence Content Type

@KaiMunechika could you please confirm if instances of this new content type show up in the V2 API at /pages/{ID}/ancestors, similar to how whiteboards are represented there?

Our apps require the ancestor line to be complete for correct operation.

Also I was wondering what the plans are for making the content of these objects available to apps via the REST APIs. Atlassian keeps adding functionality that is invisible to us and our customers are (rightfully) requesting compatibility with smart links but we can do nothing without proper support in the REST APIs.
Currently we have to tell them ‘Yes we know it’s not working, don’t use it’, which is not satisfactory for anybody.
