 Another piece here - if you register a shortcode now without a valid
 callback, you get no notice in the logs and nothing happens to your
 shortcode (it isn't parsed).

 [attachment:32445.diff 32445.diff] is all of the code that is required to
 make shortcode registration possible in `default-filters.php`. The only
 major diff is having to load `shortcodes.php` before `default-filters.php`
 in the bootstrap.

 In my patch, when a shortcode is being parsed and doesn't have a valid
 callback, a `_doing_it_wrong()` is fired. `_doing_it_wrong()` can't be
 called on `add_shortcode()` in `default-filters.php` because i10n is not
