These are by no means part of the notion of a store, but rather are things that happen to use stores. (Or put another way, there's no way we'd make them virtual methods any time soon.) It's better to move them out of that too-big class then. Also, this helps us remove StorePathWithOutputs from the Store interface altogether next commit.
