/**
  * DO NOT USE THIS METHOD!
  *
  * Seriously, you probably don't want to use this method, except from within
  * this class.
  *
  * Although it may seem similar to Title::newFrom* or User::newFrom*, chances are slim to none
  * that this will do what you'd expect.
  *
  * Unlike Title & User etc, a post is not something some object that can be
  * used in isolation: a post should always be retrieved via it's parents,
  * via a workflow, ...
  *
  * The only reasons we have this method are for creating root posts
  * (called from PostRevision->create), and so when failing to load a
  * post, we can create a stub object.
  *
  * @param UUID $uuid
  * @param User $user
  * @param string $content
  * @param string $format wikitext|html
  * @param Title|null $title
  * @return PostRevision
