 Replying to [comment:233 dd32]:
 > Once @jorbin's [attachment:17817.26.diff] is in, can't
 [attachment:17817.25.diff] just be a check on `function_exists(
 'add_filter' )` and use the API when available, falling back to directly
 modifying when it's called before initialisation?

 It doesn't need to wait for [attachment:17817.26.diff]. In the test suite,
 `phpunit/includes/functions.php` is loaded, it plays some funky music,
 then `wp-settings.php` is loaded - `WP_Hook` will be loaded the same
 before or after whatever the fix for #37707 is.
