I would like to dig into point 2 a bit. Do you think this is a matter of degree, or of kind? Does security, in this, imply a network connection, or some other way that exposes your application to vulnerabilities, or is it something else? Are there any other categories that you would treat in a similar way as security, but to a lesser degree, or that almost meet that threshold for a special category, but don't?
