Comment:

 At the end of `admin.php` WordPress fires a custom action for requests
 that include either `$_GET['action']` or `$_POST['action']`
 [https://github.com/WordPress/wordpress-
 develop/blob/6837a90e49e82192224472ac35fe2a9cc7a9e2ac/src/wp-
 admin/admin.php#L408-L420 (code reference)].

 The firing of this action does not require a query string parameter to be
 set, as such making this change would need to consider backward
 compatibility for plugins POSTing an action to `/wp-admin/admin.php`
 without a query string component.

 As a proof of concept, I've created a
 [https://gist.github.com/peterwilsoncc/cef6473cc0cb449fddd8438e4fa9e5b8
 mini-plugin] to demonstrate the use of `admin.php` without a query string
 parameter.

 @masoudin You are correct that the user experience could be nicer for
 people visiting `admin.php` without any form data (either via POST or GET)
 but the existing pull request will require a little refactoring to ensure
 that backward compatibility is retained.

 I've removed the version from this ticket as enhancements don't require a
 version be specified.
