 While working on the [https://make.wordpress.org/core/2016/10/18
 /preferred-languages/ Preferred Languages] project I noticed that it's not
 possible to hide the `English (United States)` option in
 `wp_dropdown_languages()`.

 In my case, I do not need the en_US because of the way the UI works: When
 I do not pick a language from the dropdown, en_US will be the default.

 While I added a workaround using JavaScript, I think there should be a) a
 `show_option_en_US` parameter or b) a filter (e.g. `$output =
 apply_filters( 'wp_dropdown_languages', $output, $languages, $parsed_args
 )`) at the end of the function. Or perhaps even both.
