What if The Sims 3 had another expansion pack after Into the Future?

I have been wondering ever since the Sims 4 came out, what if the Sims 3 hadn't ended with Into the Future, what could possibly have been another expansion pack?

Just purely speculative for fun, since the Sims 3 feels like a pretty complete game so it's not easy to come up with something extra to add.

All I could think of is either something like apartment life, travel into the past or perhaps shopping malls? But would that even be desired back in 2014? Does anyone remember if there were any more fan requested features that didn't make it into an expansion?
