 For a few reasons, it should be possible to prevent
 `count_many_users_posts()` from performing its query.

 The first scenario comes into play when a plugin, such as Co-Authors Plus,
 removes the default count column. The `WP_Users_List_Table` class calls
 the function regardless of the columns presence, meaning the counts are
 never used.

 Another scenario arises when a user has many, many posts. In one example,
 a user that is alphabetically first has 65,000 posts, which even on a
 performance-oriented host can take several seconds to count. Since the
 counts aren't cached, the delay can become burdensome when navigating
 through the users list.
