> Without a class or some system that keeps some bookkeeping data around with methods, every function has to have that bookkeeping state passed in as a handle, and all of a sudden all functions need to know something about how setup works, as opposed to what it does.

Classes make so much sense for me in this space, that I can hardly see why people would defend not using them.

Additional to your points, having things in classes with clear interfaces makes it possible to easily integrate new underlying functionality without changing the contract. For example you only store things on S3, have a nice class with store methods and so on. You can just add another different storage backend. How would you do that using functions only? If they also need to take care of setup? A nightmare.
