I add pages to the site that appear on the footer but not in the main nav

I know with concrete5 sites we are meant to think of them as being Trees but how does everyone out there deal with foot links, pages like terms and conditions/privacy policies sitemaps.

I am curious as to see how you all do this. Do you add these pages to the sites, first level or create a separate branch off so you can use an autonav?

Currently I add them to the home page with exclude_nav set(they dont then appear on a the sitemap page that uses the autonav)

Then I add them to a global block, normally a content block with links to the pages I need. (just about to play with Jordanlevs brilliant manual nav addon)

There has to be a better way of adding these pages? can anyone through some suggestions at me.

Thanks
