" Is it really worth it?"

Not in my opinion. These cells store multiple bits by using multiple voltage levels instead of just on/off, high/low or +ve/-ve- ie its an analogue system with all its inherent problems. There's a reason we switched from analogue to digital computers 70 years ago and those reasons haven't gone away. One of those reasons is that as components age the charge they can store drops. Thats not a problem if its binary since generally it has to drop a long way before a 1 becomes a 0. However if you have multiple analogue voltage levels it won't take much degredation to flip a 4 to a 3 or 3 to 2 etc.
