I can think of a few aspects where avif is limited.

12-bit is fine for delivery, but it's not enough for authoring. Cameras are typically 14-bit and during authoring you'll want some footroom on top of that.

Also avif is not usable for lossless: it is slower than png and often worse. Lossless is crucial for authoring workflows.

For high-fidelity lossy compression, avif can be worse than even jpeg.

Avif cannot do CMYK at all, so for printing use cases it is not usable.

Basically it is targeted at web delivery, but it's not really a general-purpose image format that can be applied in a broad range of use cases.

Seemingly half or so of images delivered anywhere currently are VP8-image (webp). You'd expect those to be AVIF instead in the coming years, which is obviously very much superior.

Forget lossless originals, this is about the average images that users see online, like 1000x1000 (or smaller) and 200kb (or so).
