there is no broadly agreed model of what that consent form might look like.

Actually there is: https://commons.wikimedia.org/wiki/Template:Consent

So images like this one would have to be deleted:

http://en.wikipedia.org/wiki/File:Michelle_and_Barack_Obama_paint_at_a_Habitat_for_Humanity_site.jpg

That image should be tagged with {{consent|published}}, which states the following:
" This media was copied from the source indicated, which adheres to professional editorial standards, allowing the status of consent to be reasonably inferred."
Thus there is no reason it should be deleted. There are several such options available with the consent template.
