It is getting its try, actively, in libjxl. People like to pretend AV1 got infinite resources; the reality is myself and one other contributor produced the vast majority of the image gains. I built Iris-WebP and aperture-alpha myself, from scratch. As a compression engineer, I think JXL is way, way harder to work with, and it would've taken me a lot longer. libjxl has community contributors, it is just an uphill battle with a codec like that. Same as WebP is an uphill battle due to its format restrictions.

That’s the thing, though: libjxl development hasn’t seemed all that active in recent years. The community contributors you mention seem quite far from driving the development, and some of them say that the usual devs have been busy with other projects (including jxl-rs as of recently).

I would not suggest that, but in another comment here you yourself say that SVT-AV1 (which you compare to JXL favourably in your article) has seen active involvement from ‘Meta, Netflix, Intel, independent contractors, and others’ – not to the community fork SVT-AV1-PSY and its successors contributing their improvements back upstream.

I can believe that JXL may very well be more difficult to work with, but am I wrong to assume you’ve been able to continuously focus on your own encoder (and apply your experiences from your earlier work on SVT-AV1)?

Yes, but for speed which means a lot of SIMD plumbing, the larger workforce certainly benefited AV1 codecs!
