 > These should either be statically named hooks, or a better way of
 clearly passing different formats and number of data to the hooks is
 needed.

 We can't statically name the hooks across the board, as some of the hooks
 are covering multiple screens. eg. the
 [https://github.com/WordPress/WordPress/blob/acd764a1d3e599797a5d875f5721f76f81638cf9
 /wp-admin/edit.php#L178 edit.php handle_bulk_actions-* hook] invokes
 `handle_bulk_actions-edit-post`, `handle_bulk_actions-edit-page` and
 ``handle_bulk_actions-my-custom-post-type`.

 If we want statically named hooks here, perhaps we could change all hooks
 to use a single hook, `handle_bulk_actions`, and expect developers to
 perform the screen check in their callback. Since different screens will
 include different contextual data, perhaps we consolidate it in an array
 in a `$context` argument. eg.

 {{{
 #!php

 // For users.php
 $context = array(
   'user_ids' => $userids
 );

 // For network/site-themes.php
 $context = array(
   'themes' => $themes,
   'site_id' => $site_id
 );

 // The hook invocation might look like this
 $redirect_to = apply_filters( 'handle_bulk_actions', $redirect_to,
 $do_action, $context );

 // A bound callback might look like this
 add_action( 'handle_bulk_actions', function($redirect_to, $do_action,
 $context) {
   if ( get_current_screen()->id !== 'users' ) {
     return $redirect_to;
   }
   // Do something with $context['user_ids'], modify redirect link
   return $redirect_to;
 }, 10, 3 );
 }}}
