Can you please explain what exactly you want to implement then can I give you a better idea for implementation.
We use pages to manage content 'blocks' which are then included in other pages.
For example, if we have special shipping information that is included on certain product pages, we'll create a page and then use some logic to output the page contents within specific product pages. In this way the content may be centrally managed.
This works fine with the current pages set up - wondered if would work the same in the new one.
This is an accepted solution.
I've explored this internally and this object will not render sections of a page.
Hope this helps,
