Comment (by engelen):

 Thanks @aaroncampbell, you've voiced my opinion perfectly. `has_shortcode`
 is not intended as a function for a simple string match on a content
 string. It's intended for checking whether a piece of content contains a
 shortcode that gets executed. Nested shortcodes aren't executed by
 WordPress core, because the raw content between shortcode opening and
 closing tags is handled by the shortcode's callback function. Thus,
 `has_shortcode` should not look for nested shortcodes by default.

 However, this is purely theoretical: this isn't a bug, it's intended
 behaviour (otherwise, the function wouldn't fully parse the content for
 shortcodes in the same way `do_shortcode` does), and we thus have to
 maintain backwards compatibility. Therefore, `$recursive` must be `false`
 by default.
