Hardcore in realms

You should allow hardcore mode in realms. I have seen previous posts about this where the author suggested that the operator be able to respawn people, I disagree with that. I think that when a player dies they should be allowed to spectate, and when the final person dies the world must be deleted. I think that this would be quite a fun way for friends to experience Minecraft together. As much as I love the current multiplayer vanilla experience and building worlds for months or years, I think this would be an interesting new way to play vanilla multiplayer.
