Correct

But just in general all of it needs to be redone when Webp is more widely used.

https://developers.google.com/speed/webp/

And in that case almost everything can be a webp - animations, transparency, lossy for compression or lossless if need be. You can still burn the bathroom selfies if you want. Except vector, you still want SVG for those.

WebP will never take off due to Apple not supporting it. If Apple chooses to support the AV1-based AVIF, that will become the next big format instead. Apple has joined the AOM so there is a reason to believe they will (but then again they also joined the Blu-ray consortium and never shipped a Blu-ray drive)

webp can be a bad choice because it is always chroma-subsampled. png and jpeg support full chroma.

Anything coming off developers.google should be avoided like a plague.
