Comment (by mikeschroder):

 I'm reviewing the patch now, and will leave further notes if there is time
 before it's committed.

 My testing from the plugin so far has worked as expected.

 I wanted to leave a note that I support this particular implementation /
 method, and think it's great that there has been as much community-wide
 discussion about it so far. It's made the feature much better than it
 would have been a cycle ago!

 I also had the concern about WebP being larger in some cases (which was
 confirmed during image quality testing), and dropping the images that are
 larger solves this concerns.

 It's worth noting that when WebP is smaller, which in my testing so far is
 common for smaller resolutions even when the largest sizes are bigger, the
 savings percentage-wise are quite significant.

 I think this feature has the chance to make a big impact on load times and
 bandwidth on the web at large.

 It is a big change, and I support landing it early, as is currently
 planned, so it can get thorough testing in core.
