Requested feature overview description.
I noticed that the "Post.register()" Javascript functions in the HTML of all pages which show post results contain all the same information about each post as the "/post/index.json" API endpoint shows, except for the last 4 JSON entries, which are "has_children", "children", "parent_id" and "artist".

Why would it be useful?
It could help script makers and would allow them to make fewer requests to the API, since common data is already in some pages.

What part(s) of the site page(s) are affected?
Any page which show post results.

Edit: oops, posted the thread before finishing the title, sorry.
