Indeed it's not required to implement issue6389.
I uploaded a first draft on review40811002.
I'm if it's really required to be explicit on button depends, as I see no case where the depends will be missing and the test should pass. So I'm thinking if it won't be better to compute the buttons dependencies on modelview.
