Comment (by joemcgill):

 This is a tricky one. If there's a way to calculate the actual image width
 that will be applied using `object: cover` at different break points, then
 we could update the `sizes` attribute accordingly. It's worth noting that
 `calc()` works inside `sizes` attributes. If that doesn't work, then a
 possible approach could be to estimate when the image will be larger than
 100% of the screen size and do something like `150vw`.
