Please consider adding srcObject or some such to <img>

I'm pretty sure this has implementer support already, it just lacks a specification and tests. If someone is interested in doing this work I'd be happy to give guidance.

Is this our tracking issue for adding srcObject everywhere, and in particular expanding it to accept Response objects? I could swear there were more open issues somewhere about that.

Fetch has one or two similar issues if I remember correctly. I would be happy with Blob alone for now, to reduce the need for URL.createObjectURL(), but Response seems nice as well.
