As the title says, is there a similar behavior like hook_views_ajax_data_alter in Drupal 8 like in 7? If not has anyone achived the same result programatically?
Mybe you can try implementing an AjaxResponse Event Subscriber and alter the commands onResponse : an example of this is here : https://www.linkedin.com/pulse/how-alter-ajax-commands-view-response-drupal-8-dalibor-stojakovic/
