Out of curiosity, all other debates aside, would it not be helpful to have (either built-in or as a separate plugin) a way for Rails to run a simple set of sanity checks on the SQL it passes to the DB server? For example, checking to make sure that the generated SQL doesn't contain "--" wouldn't fix the underlying problem, but it could be used to prevent the exploit from ultimately working (and, if someone tried this, would alert you to that fact, assuming the error was logged). I get that this would create some performance overhead, so it would ideally be configurable.
