Blame Adobe. For what they charge for Creative Suite it ought to have supported it a long time ago.
My webcrawler sucks down a lot of WebP images, at least it did before it got the smackdown from Cloudflare.
Adobe Photoshop has support for WebP (through "Save as", not "Export") but I don't think WebP is important.
