It's worth pointing out that browser support is a tiny, but important, part of overall ecosystem support.

TIFF is the dominant standard for certain hardware and processes for digitizing physical documents, or publishing/printing digital files as physical prints. But most browsers don't bother supporting displaying TIFF, because that's not a good format for web use.

Note also that non-backwards-compatible TIFF extensions are usually what cameras capture as "raw" image data and what image development software stores as "digital negatives."

JPEG XL is trying to replace TIFF at the interface between the physical analog world and the digital files we use to represent that image data. I'm watching this space in particular, because the original web generation formats of JPEG, PNG, and GIF (and newer web-oriented formats like webp and avif) aren't trying to do anything with physical sensors, scans, prints, etc.

Meanwhile, JPEG XL is trying to replace JPEG on the web, with photographic images compressed with much more efficient and much higher quality compression. And it's trying to replace PNG for lossless compression.

It's trying to do it all, so watching to see where things get adopted and supported will be interesting. Apple appears to be going all in on JXL, from browser support to file manager previews to actual hardware sensors storing raw image data in JXL. Adobe supports it, too, so we might start to see full JXL workflows from image capture to postprocessing to digital/web publishing to full blown paper/print publishing.
