This kind of works fine until you have many customers. If you have < 5 customers, then this works fine. If you have > 10,000 customers, then this works fine, because you can rely on analytics. If you have 100 - 500 customers, then it kind of breaks. You can't rely on analytics because those customers are too important, and you can't rely on 1-1 interaction with engineers because there are too many customers to consult on each change.
