 Replying to [comment:29 michaelbourne]:
 > What kind of testing did you have in mind? Happy to help here as I
 greatly want to see this added to core. I also saw no downsides in my
 tests with adding it to all images, but willing to deep dive it if needed.

 Probably showing how specifically `decoding=async` improves performance in
 results from WebPageTest, showing before/after.
