The rarely-used features that have to be enabled for them to work also broke things pretty obviously. I figured that if anyone ever did decide to use those features, they'd end up fixing the vulnerabilities in the course of fixing other bugs. Also, they only allowed people to get broken HTML (with no way to insert valid HTML tags, so no chance of them sneaking scripts in) in their posts. I'll have to look through the code to see if I can find them again.
