 I checked that the places storing data in the `'counts'` cache group have
 proper way to delete the data in cache on updates. For example,
 `wp_count_posts()` stores the post count, and `_transition_post_status()`
 deletes the count. So could we change the `'counts'` cache group to be
 persistent? This can reduce the repeated counting queries to the database.
