Well of course if you are trying to ressurect someone then sure the first thing you need to do is actually confirm that the person is dead. That's just... logical for any sort of ressurection, not just the Krakoa ressurection protocols. What if someone tried to bring back the X-Men back to life when they were faking their deaths during the Outback era? We didn't see that because we, the readers, knew they weren't actually dead, but now that the mutants are on charge of their own ressurection it's obvious they need to face these questions.
