By ericof:

If you used a Deco page as default item in a container (a Plone site, for instance) when you added tiles they would end up being written on the container not on the Deco page.

I decided to use the ILayoutAware to check if the context was the right place to write the annotation after talking to @davisagli or @robgietema at the sprint.
