Comment (by nacin):

 post_exists() isn't used anywhere in core, but importers make use of it to
 identify if a piece of content that is trying to be imported, was already
 imported previously.

 In general, it should surely not be used. If it is a problem, perhaps we
 can deprecate it and copy its logic into a method of the WP_Importer
 class. Certain importers like the WXR importer could make use of GUIDs.
 Others, not as much.
