I think issue 4 is critical.

For issue 7, I would think that metadata could be omitted for
resources from the same origin because that's the source of the
metadata in the first place and so must be trusted.

I think issues 10-12 need to be resolved either by omitting these
elements from the v1 spec, or including a progressive hashing mode.

Additionally, srcset[1] contains some challenges and probably merits
an issue in the draft.
