Enabling the Extra Widgets feature in Jetpack brings along with it jQuery. For sites that weren't loading jQuery before that can be a big deal.

Describe the solution you'd like

I'd like to see the Extra Widgets feature updated to not require jQuery - a.k.a. vanilla JavaScript.

Additional context

I recently ran tests under slow mobile conditions and just enabled the Extra Widgets feature increased the start render time by 23%. The 317% increase in the amount of JavaScript being loaded on the page was the major contributor there. Of that jQuery is a big chunk, coming in at 94 KB.
