* an appropriately localized version of the template; or the
* template fetch could be redirected to a 'stable revision' of
* the template. If the returned RevisionRecord does not exist,
* its title will be added to the page dependencies and then this
* hook will be invoked again to resolve that title. This allows
* for fallback chains (of limited length).

* @return bool|void True or no return value to continue or false to abort
