Support for Client Hints

[PeterDeKeer]

Do you plan to support Client Hints in the future?

Since you support 'optional WebP' for browsers that support it, it might be possible to implement?

Thanks!

I wasn't aware of client hints, but they look awesome and not too hard to implement.

The only downside I see is reduced cacheability due to needing to include the DPR and Width in Vary, which will make responses not cacheable unless there are exact-match DPR and Width request headers.

Indeed, less cache but you don't need to generate an image for every pixel width. You can be 'lazy' and take 100px steps or look at this solution from cloudinary: http://cloudinary.com/blog/introducing_intelligent_responsive_image_breakpoints_solutions Being lazy is good too!
