Not sure if this could have had any effect on the outcome of this, but didn't the head of the FAA resign abruptly like 2 weeks ago because of some power struggle with Elon Mush who was targeting the FAA for cuts under his Dept of Efficiency title?
any subsequent rules/restrictions would then come from FAA. So i dont think that this accident and resulting changes would be delayed due to no FAA director. Someone has to have the authority to enact new rules/regulation changes.
