As far as I can see, Safari UA is not blacklisted for webp, so if the browser send image/webp as a navigational header, pagespeed will send the webp image

Great news!

@Lofesa The pagespeed can server webp to any client but the problem is that the Safari cannot read webp. In other words you have to enable the UserAgent Append to ensure that your users can see your webp content successfully --as jpeg ofc and NOT as webp.

Well... you can configure pagespeed to serve webp to all clients.... or not.
pagespeed ServeRewrittenWebpUrlsToAnyAgent off; that is the default.
When this parameter is off, pagespeed only serve webp images to those browser that send a navigational header image/webp. If the browser don´t send ths header, no webp is served.
I don´t know how Safari does this.

I'm trying to understand this thread. I think, as Lofessa said, that if Safari can read webp, and sends Accept:image/webp in its request header, then PageSpeed will send webp to Safari. No customization on the PageSpeed side need to be done.
I did not understand @Poseidonas response "Safari cannot read webp", which contradicts the premise of this issue.

But in any case I don't think there's any bug here.
