Lossy WebP has some crappy limitations. For example, it's limited to 4:2:0 chroma subsampling, which makes it unsuitable for high quality images. Hell, even if you restrict yourself to 420 JPEG, JPEG still comes out as having a higher quality ceiling than WebP. And yes, it does beat MozJPEG and libjpeg-turbo in file size sometimes, but newer JPEG encoders like jpegli crush WebP in size completely across the entire quality spectrum.
