At the moment i have 5.7-alpha-49645 installed and i see a LOT of migrate notices on WordPress core.js, iris.js (colorpicker) etc. Is there any information on when they plan to also migrate the core itself to make it compatible with the most recent jQuery version without jQuery.migrate?

I found it hard to debug / migrate your own code if you always have like 20 notices from the WordPress core in your console.
