  I agree that it can still be used in a lot of applications, but this would probably restrict its use in everyday items, such as over-the-counter magnetic bearings,long-distance transmission lines, or consumer electronics (RoHS). Lead batteries for cars are a bit special, as the whole supply chain goes both ways for recycling, while batteries are rather self-contained and not usually exposed to harsh environments. Though I suspect you are right in the end, as it's a matter of judging the risk vs reward, I wouldn't be surprised if other materials with a similar structure end up performing similarly. Pb is also quite hard to use in integrated circuits, as far as I know. I am no material scientist, but it could be due to its low melting point or tendency to contaminate other metals.
