I think such template is a great idea. Don't know how doable integrating it into UBB.threads would be, though. For sure that kind of customization would complicate UBBT upgrades.
One thing to keep in mind is it wouldn't be applicable to forums such as FTM Feedback and the Lounge. So I see a need for either an Admin option to implement it on a forum by forum basis, or a quick and easy way for folks to click through the form without completing it. The former would, I'd think, make the project more complex, while the latter would increase the likelihood that posters who shouldn't would skip through it.
