It's handy to do binding without validation when you want the user to be able to leave a form to an intercept page before they are done working with the form. My exact case is a form that contains a user-selected photo. The best way to allow a user to select a photo is to take them to another page so they can browse thumbnails, upload new images, whatever, but it's not expected for them to loose the information they've already entered or to be required to complete the entire form before selected a certain piece.
And yes, I could just make photo selection a new page (which I will do if this patch doesn't go through), but this seems more elegant to me. Making every little step a new page in a wizard reeks of webapp to me, and I like to try to get more of a desktop experiance. Sure it's not something you going to run into every day, but if you do, it's really nice to be able to control form behavior at this level.
