      // Many contrib modules assume that query tags used for access-checking

      // purposes follow the pattern $entity_type . '_access'. But this is

      // not the case for taxonomy terms, since core used to add term_access

      // instead of taxonomy_term_access to its queries. Provide backwards

      // compatibility by adding both tags here instead of attempting to fix

      // all contrib modules in a coordinated effort.

      // TODO:

      // - Extract this mechanism into a hook as part of a public (non-security)

      //   issue.

      // - Emit E_USER_DEPRECATED if term_access is used.
