The impact of removing jQuery on our web performance

I'm generally not a fan of throwing pointless wheelbarrows full of JS libs at a website. And would usually welcome any site announcing they're stripped out such cruft.

But, as someone alluded to in the comments on the GOV.UK site; the write-up here is pretty misleading in how it suggests the changes have reduced the page load time of every page on the site by ~32kb.

After the first page load, the browser would have cached the ~32kb jQuery library anyway. So this does seem like a lot of effort [and taxpayers money] for a one-time ~32kb saving.
