Being that Webp is a Google thing I don’t trust it at all. Along with almost all browsers being based on Chrome the web is quickly becoming Google’s back yard. We won’t see the error of this path until it is too late. I think building this into Core and defaulting it is a mistake. I have and always will be in favor of user choice, be it this or auto-updates. Its very frustrating that as genuine alternatives begin disappearing those left are beginning to force new, more restrictive standards on us.
