We want to have multiple levels of security. We not only try to make sure that there are easy interfaces (but yeah, I don't force people to rewrite - I sadly don't have a cadre of slaves at my beck and call ;p), but it's also always a good idea to have interfaces that are bug-resistant even in the face of people actively not using the better interfaces. So having good interfaces that are harder to have bugs in does _not_ mean that we still shouldn't have defensive programming practices anyway. The combination of the two means that a bug in one layer hopefully gets caught be the other layer.
