There is also a new experimental Fast Lossless mode in JPEG XL as well, but it was developed after this post was written https://github.com/libjxl/libjxl/tree/main/experimental/fast...
The article literally compares it to others. It might not have been finalized at the time of writing, but it's not like the author was unaware of it.

For this article the context is for use in browsers, and the main metric being measured is compression ratio.
I would love to see an estimation of how small real world images would get if we could calculate their Kolmogorov complexity. Aka if we could find the shortest program that produces the image as output. Some images obviously would become very small. For example an image that is all blue, a spiral, the flag of the United States, the Mandelbrot set ... But what about the average portrait for example?

This works absolute wonders if you are talking about images with a limited amount of colors and without many gradients. I use it to compress screenshots of websites, which, if you think about it, are mostly large blobs of uniform colors with hard edges. I also use it every time I want to include a screenshot from my desktop in some publication or email. The savings in filesize are too good to be true without any apparent loss of visual fidelity.
I'd imagine the benefits of changing to something more modern/efficient aren't worth the cost/time involved other than in esoteric situations given that most end users have high bandwidth connections and bandwidth costs typically aren't too significant?

Mind that TIFF is only a container format that can contain any arbitrary codec you like; it can be uncompressed pixels, RLE compressed, it can be a PNG, a JPEG XL, even lossy JPEG or WebP if you'd like.
Saying your image format is TIFF is roughly as useful and conveys as much information as saying your video format is MKV.
For web graphics, isn't a mix of PNG/JPEG good enough generally speaking?
