I still think this option should be an opt-in instead of being default and force people to increase disk space tremendously. Many sites already have a image delivery/optimization system like Cloudflare, imagekit, optimole etc. That takes care of image optimization and WebP. So sites that already have such flow in place, they don’t want any WebP on disk for good reason.

But on the fly image generation even for JPEG would be rad. But I’m not too optimistic about it though.

I just hope no matter what the performance team decide to do, they make this an opt-in system and not default.
