In fact, the OpenBSD policy has always been what Greg articulates: "always update to the
latest -stable kernel update". Theo has made this argument for years: Nobody has much time or
patience for classifying bugs, and even if they did, it's actually quite tricky. Any
classification will contain so many false positives and negatives that basing your security
decisions on it would be foolish. Fix and patch bugs rather than philosophizing over their
nature.
