One quick look at the UI (https://signal.vercel.app/_next/static/media/screenshot.dc00...) and with the experience of developing bigger stateful UI applications with jQuery (and Backbone.js, and AngularJS, and React, and...), I would wager that if they were using jQuery at this point, they'd be fighting way more than they ended up doing.
I agree with grand-parent though that it seems like an excessive amount of rewrites, don't get me wrong.
