Google has yet to demonstrate that WebP produces better image quality at the same or smaller file size than what's possible with JPEG. Until Google can kill it on that test, nothing else really matters because the format has no features above and beyond JPEG and none on the roadmap. That means all WebP has going for it is the quality size argument and that's yet to be proved. Google has shown a lot of images that are smaller file sizes and look clearly worse to even the untrained eye. Show me same quality at a smaller size or better quality at the same size and then WebP can claim it's got something going for it. That hasn't happened yet so it's a negative when stacked up against JPEG and most of the current JPEG alternatives.
