Right, WebP was almost certainly a mistake in hindsight. Whatever advantages it had weren't worth a decade of ecosystem fragmentation. Isn't learning from mistakes and not repeating them a good thing?

I don't think AVIF is a good example of this though. All major browser makers were members of the consortium that created AVIF.

On the contrary, the webp push didn't really hurt anything... there were (IIRC) no major exploits related to it, and it sees some use. I wouldn't say it was a mistake.

But it was a tremendous amount of effort and promotion on Google's end for a relatively narrow format.

I would seriously disagree. Plenty of CMSes switched all their photos to webp resulting in a huge loss in quality.
