What if a modification doesn't need updating? Many modifications from 3.5.x still work fine with the latest version of 3.6.x without any changes.

I agree that there should be some kind of mandatory distinction between supported and unsupported otherwise what's the point of marking either way? I've seen unsupported hacks that are well supported and supported hacks that haven't seen a reply from the author in 6 months or more.

One way I can think of would be to give the option for users who have installed a supported modification to nominate it as unsupported if they aren't getting any support. After X votes, it sends an email to the author asking if they're still supporting it and if not, could they change the supported tag. If there's no response (to the email or in the thread) from the author then the change is automatically made.
