Comment:

 I am not fond of the snowflake code for a feature plugin here. While
 WordPress has a commitment to backward compatibility it is going to have
 to stick around for a long time.

 Is there a reason the use of `do_action( "update-custom_{$action}" );` in
 `src/wp-admin/update.php` wasn't expanded to allow the use of custom
 updaters within the built-in actions?
