 stack.

 You are correct. Bad example on my part for `WP_Query`; I researched in
 haste and was not paying enough attention to the specifics.

 But still a good example for need of `'context'` argument.  And there are
 also good examples for need for `'context'` passed by WordPress core for
 calls to `new WP_Query()` in:

 - `wp_ajax_query_attachments()`
 - `wp_link_query()`
 - `wp_dashboard_quick_press()`
 - `wp_dashboard_recent_drafts()`
 - `WP_Widget_Recent_Posts->widget()`
 - `wp_nav_menu_item_post_type_meta_box()`
 - `wp_get_associated_nav_menu_items()`
 - `get_popular_posts()`
 - `delete_search_results_template()`
 - `get_posts()`
 - `wp_get_post_autosave()`
 - `query_posts()`
 - `url_to_postid()`
 - `wp-settings.php`

 Then of course there is the large number of places that `get_posts()` is
 called as well, and several other functions that ultimately call `new
 WP_Query()` and/or `WP_Query->get_posts()`.

 ''Not'' having an explicit context means that the plugin code has to
 ''"guess"'' at it's context using URL parameters, `$pagenow`, `$typenow`,
 `$current_screen` and any number of other environmental clues that can
 result in a false positive, the worst being `debug_backtrace()`.  By
 adding an explicit `'context'` for all calls to generic functions
 throughout WordPress core plugin authors could precisely ''"scope"'' their
 hooks to operate only when needed and not when they are ''"best guess"''
 needed.
