I don't think we should care too much about that. It's a failure on the part of the SP. They've been told they need to keep their metadata regularly updated, and they have chosen not to for whatever reason. So as long as you have understanding library colleagues, and maybe as Adrian says you're willing to go the extra mile to give the lamer providers a prod when you notice them, I'd say it's not your fault and don't worry about it. Might be a different story if you have highly-strung library colleagues though :) This problem is going to keep biting the lamer providers over the next couple of months, so you'd hope they'd get their act together and sort it.
