Currently, there is no way for a custom module to alter the AjaxResponse before being sent on webforms with Ajax enabled.

It would be great to have available a hook to be able to add or alter the commands that are to be sent.

The solution is going to be to create a WebformViewResponse object which can be altered via an event subscriber.

The attached patch contains WebformSubmissionAjaxResponse object which is returned by all WebformSubmissionForm ajax responses.

Please note: Drupal is moving away from alter hooks and EventSubscribers are the recommended way to alter a request and/or a response.
