While I cannot speak for the original `srcset` proponents, we are in
agreement on this with Ted O'Connor, the `srcset` spec editor.

The viewport hints are still important for viewport based resolution
switching, for non 'art-direction' images that maintain their proportions
across viewports.
If good ideas on improving the `srcset` syntax were raised on the various
mailing lists and forgotten, could you please help us by linking to them?
(either here or on the public-respimg mailing list)

I agree that this section should be modified to accommodate the use of
`srcset` with `<picture>`.
