Hm, this didn't change anything hugely on one of my projects - for example, it reduced the total bundle size, but it increased the gzip'd size, so it's actually a net negative for me. But it looks like the CSS improvements actually did help.

It looks like a great idea and would probably help if I had any images in my project.

Hi! It's true that it you don't have images, the benefits are limited. Also, your CSS may become bigger at the end because we automatically improve compatibility with browser. You can disable this by setting browserlist to empty string. https://jampack.divriots.com/features/browser-compatibility/
