When you work with "dumb" containers you have to apply this logic on application level. That hurts. This is e.g. why Plomino fails on certain security challenges.

One thing that would be nice with the folderish content is to remove the special image field on news and replace it with a way to make an normal image (contained in that item) as the headline image. The same technique could be used so that any page could have an nominated headline image that gets used in listing that have preview images. I'm not really sure how this would work yet however. Maybe a reference field on all content to pick the image?

plone.app.contenttypes already switched to implementing this with a 
"lead image" behavior that can be enabled for other content types. The 
image is still not stored as a separate content item though, which I 
think is appropriate for this kind of image.
