Lets see how codeless a system like this will be after new requirements begin to pop up. It's a bit like the promises rails made many years ago: "A new webshop application can be ready to use in like 15 min.". This statement is certainly true, if your shop app has only simple/default requirements that rails ships already. Usually, that is seldom the case, and you start to implement, integrate, test and document missing functionalities for most clients out there.
