I know that, but how does it work? If you die during a quest say, battle for whiterun, and you return, where will you be? How much time has elapsed? What happened to the battle? If you're not there, the battle will be lost. If you revive where you died, chances are you'll die again if during a boss fight, or you'll be able to resurrect indefinitely and kill the boss. Another point of interest, what happens when you die during the main quest Dragon Slayer? Or specifically, what happens when you die IN SOVNGARDE? I think there will be a conflict with the machanic if you're doing the battle of whiterun. Otherwise I'd just think that instead of dying and reloading the last load, you'll wake up in Sovngarde and can escape - or stay awhile.
