Film Editor is no longer an accepted Editor attribute because it is "automatically implied"?

At the risk of sounding sarcastic, it seems bizarre that Film Editor is now a rejected attribute for the Editor section, and yet, Composer is accepted for the Composer section.  Wouldn't it be "automatically implied" that the Composer is a Composer?  Of course!

What about attributes such as "edited by" or "directed by"?   Obviously it is "automatically implied" that a film was edited by the editor and directed by the director.  You have said for many years now that you wanted the attributes to show exactly what the credit stated on the screen.  Has there been a significant change in the IMDb policy regarding this?  Will you be eliminating all attributes that seem too obvious since they would be "automatically implied"?
