Site navigation is a combination of two concerns - declaring what navigation items there are in the site, and what the structure of them is - as presented to the use.
Specifying items and structure separately is not DRY, and applications also need to have the ability to change the structure to suit them - therefore the structure information provided by a plugin is merely a guide, and inherently disposable.
