I hope the point was brought up that Webp only does lossy compression tho, while Jpeg2k Also does lossless. In light of sculpts requiring lossless compression, I'd not expect the need for a jpeg2k decoder to go away anytime soon for at least that kind of texture, alas, unless lossless textures'd get stored as PNG images. PNGs result in smaller files than Jpeg2k when the image is a classic type of texture that'd use lossless compression, like cliparts with lots of pixels of the same color, tho Jpeg2k seems to excel at lossless compression when complex images are involved.
