Motivation

Having both the current store and the Map Store in the codebase is greatly complicating maintenance, and other teams have a hard time working with the storage layer because any change has to be replicated in both stores. With the decision to no longer develop the Map Store, we should aim to remove it from the codebase to simplify both maintenance and further developments in the current store.
