I'd be happy to support the low power variants as well, but without spending a bunch of money, I have no idea what features they have and what they're missing. Its very annoying.

For anyone not familiar with caniuse, its indispensable for modern web development. Say you want to put images on a web page. You've heard of webp. Can you use it?

At a glance you see the answer. 95% of global web users use a web browser with webp support. Its available in all the major browsers, and has been for several years. You can query basically any browser feature like this to see its support status.

That initial percentage is a little misleading. It includes everything that caniuse isn't sure about. Really it should be something like 97.5±2.5 but the issue's been stalled for years.

Even the absolute most basic features that have been well supported for 30 years, like the HTML "div" element, cap out at 96%. Change the drop-down from "all users" to "all tracked" and you'll get a more representative answer.
