The way I interpret this is that if a the content of a resource can now be permanently found at another URL, the server should return a 301 status.
Yes, but it should be a "one to one" mapping:
old-page-1 => new-page-1
old-page-2 => new-page-2
old-page-3 => new-page-3
old-page-4 => new-page-4
It might be a "several to one" mapping but it will not be a "many to one" mapping.
In my case and I guess BradleyT's as well, this happens to be the homepage.
No. The new URL for a deep content page will be another deep content page, or at worst a section index page. It will never be the root index page.
In particular, whatever the new page is, it will never be a replacement for dozens or hundreds or thousands of old pages. That's just not a plausible site architecture. The old URLs should return a 404 or 410 and the error message can be customised on a per-directory basis especially for those URLs.
