We need more rabbithole buildings such as University and Batuu had!!!

I don't mind rabbit holes for some bits, like the skill classes in university but I won't go as far as asking for them because I like to accompany my sims to restaurants and such. But if we keep getting worlds with tons of empty shells, they might as well be useful as a rabbit hole. For example in snowy escape they could have used a building to sell ski equipment, no just vending machines.
