It's a big deal :(

JPEG artifacts are literally a meme, normal people are aware of this stuff.

I hold the extremist view that had we decided to use .png for lossless webps, it would have been an overall net gain - in people's minds "png" maps roughly to "whoever last touched this image didn't do anything evil to it" - very few people care how the data is actually encoded.
