What is JPEG-XL and why wouldn’t one continue to use PNG?

Up to 46% compared to PNG is more than a bit extra. It’s also both loseless and lossy and supports backwards compatability between legacy JPEG. Among many other modern features.
And PNG is so old that it lacks basic modern features like HDR support.
The only competition to JPEG-XL is AVIF. Though both likely to coexist as they have different strenghts.

Its not backwards compatible. I don’t know where you got this idea from.

Creating two copies of a file isn’t backward compatibility. Thats what devs are doing now with webp. One webp file, and one joeg file for clients who cant render webp.
Now if you could open and view a jpeg xl file without having to upgrade your app/browser/whatever — that would be backward compatibility.
