When you are faced with a poorly documented wired network and want to get something installed on the quick with the least friction possible or where the organisational structure means that you cannot make any of the required changes easily, controllers make it pretty easy to add a box that you tunnel all the traffic back to to deal with it in one or a few places. A case of pragmatism, certainly perceived pragmatism, winning over technical merit. It is certainly not ideal.

When dealing with guest traffic, it can make people feel warm and fuzzy that it has been overlayed and thus isolated from the existing network, certainly where the network is being used for business purposes. It avoids having to think as much about how you would do it in a secure way otherwise.
