Loading the images at the right dimensions is important for several reasons:
- More work client-side to resize the images (CPU intensive)
- Higher bandwidth use than necessary, leading to slower page rendering
- Marginally higher client-side memory use
Overall this can hurt the user experience, so it would feel like a regression.
I would instead prefer to look for a solution allowing to keep this parameter on, while returning image of better quality.
So I’m currently -1.
PS: Having the capability to return image of good quality at different dimensions is also an essential feature of my srcset proposal.
