Comment (by obenland):

 Replying to [comment:21 DrewAPicture]:
 > * I think ''because'' of the deprecated notice and ''because'' we're
 talking about default themes, we need to update the defaults back at least
 a year, so Twenty Fourteen and Fifteen
 Twenty Fifteen already uses the new way. Again, if we updated Twenty
 Fourteen we would break backwards compatibility with everything that is
 hooked into `wp_title_parts` and `wp_title` on sites that use the theme.
