Like Frito Pies and Hot Dish, some people love their jankiness. I was actually comforted by my adoring fan getting stuck in the chairs and table in my ship.
Classic Bethesda bugs make me feel right at home. Also, having the spell system repurposed was classic BGS.
To be fair, why make an entirely new system that does the exact same thing? For instance, I don't see anyone complaining that the Action Points in Fallout 4 essentially function as Stamina in Skyrim.
