The problem is, but we are getting off topic, that in order to get a rich snippet, Google must, among other things, be able to reliably identify the *main* entity in the page, because a snippet summarizes a page as a whole. When you mark up all entities, it can be more difficult for a search engine to find the most important one.

In theory, one could use the mainContentOfPage property of WebPage to indicate the key entity, but that is currently not working, afaik.

So when you want to use the advance features of schema.org, you need to be pretty knowledgeable about the underlying technologies, unfortunately.

SiteNavigationElements, WPHeader, WPFooter, WebPageElements, etc, etc. All of which have their role but which aren't considered 'main content' and therefor don't or shouldn't generate rich snippets (an occasional mark up error can cause Things to show up though, even if contained in a <aside> or <footer>).
