We had the same sort of issue where I work. When we first rolled out LANDesk we thought the uninstall association was the greatest thing since sliced bread. Come to find out there is not enough control over it. One thing could go wrong and you could end up having uninstalls go off on thousands of machines. So we in the end got rid of them. I think the uninstall association would be awesome, but only if it were able to be manually triggered by the LANDesk system administrator. Its a very dangerous setup, if I am you, and I was at some point, I get rid of those associations. You will still have the uninstall packages and can use them when you want to use them.
