At first I interpretted Michael's statement to mean that sometimes you might
reasonably choose not to meet even the basic exception-safety guarantee. But
maybe by "completely exception-safe" Michael means the "no-throw" guarantee, in
which case there may be all sorts of reasons, depending on the circumstances,
not to be completely exception-safe, no?
