Wikipedia:Articles for deletion/List of films about pianists
This is useful, non-trivial information. Regardless,  applies to trivia ''sections'' within articles, not to categories some might arbitrarily deem trivial. Also, although it's been referenced as a justification for deleting this list, I can find no section of  relevant to this list. Also, I don't think the slippery slope argument cited by the nominator should be sufficient justification in itself to delete a useful category. Why not delete any inappropriate categories that a category may spawn, rather than deleting a useful category
