Domain content permission definitions

README.txt for this module states that:

The Domain Content module does not add any new Access Control permissions.

The module uses the existing permissions from the Domain Access module.

However in the module we have an implementation of hook_perm which introduces two new permissions - configure domain content and review content for all domains. I can't find any reference to 'configure domain content' besides being defined as a permission.

Is there a reason to keep it around? I'll roll a patch once I know which way we are going with it.
