Well, I am a little disappointed how difficult Wordpress it makes to deregister scripts.
First, I got a list of all handles, so I looked it up and the handle was jquery-migrate
I then added this to my functions.php
It does nothing, although the scripts are properly registered.
What's up with the version strings, I can think of no reasons why they are still including those, should be removed in the next WP version asap, they only prevent caches from properly caching it in some cases and are annoying.
Any input on how to "properly" deregister scripts is appreciated.
