Easy is basically what most people play.
Medium is essentially what Minecraft does (the challenge being in having to get back to your gear if its in a dangerous spot)
Hardcore is permadeath.....the ghost mode is just there as @darthmorf said: to give you one last look around before you reroll and start anew.
To me, its about how hard/easy it would be to add this. If it's not bad workload wise....then why not, I suppose? That said, the mode that is the default now is likely what 90%+ play, even on PC.
