At the current state of the game I'd call it a loophole. The player avoids standard long resting mechanic to prevent a specific scene from triggering. And it serves as an argument for some people to say he isn't in fact 'evil' or controlling as ascendant. It just makes the spawn ending way less compelling and meaningful. The player gets nothing really in this path after the lovely scene at the graveyard.
