See my other comment on this thread. Even in that case you don't have to care.

  There are tons of applications where rolling upgrade doesn't necessarily work out.. anything that is even remotely latency sensitive or state-heavy, for example a game server or an order matching engine

    Every service that Google operates is released with rolling updates and is fully preemptible, including the most highly latency-sensitive services and all of the stateful storage services. Google is an existence proof for the applicability of rolling updates to services of all kinds.

      For state heavy applications, you want graceful restart even if you can tolerate hard failures.
