Gianni Rosato@Jain JXL isn't needless feature creep; that's what the video-based codecs are. You're thinking from a purely web-based standpoint here. JXL would be the only promising image codec to hopefully not need to look at another one for a very long time. I can tell you right now that professional photography, medical imaging, astrophotography, etc are simply not interested in AVIF, while JXL has the features to make everyone happy across the Web and beyond
