This is exactly what they did. Take Whitemane for example. Queues were hitting 7+ hours at peak times and would start as early as 12 servertime. They were late on transfers to the server, but eventually stopped them. Then they offered free transfers off, no one took them (they have the data and is mentioned in the other post). Their only option is to allow layers which they have.

Layering did not exist, had a specific reason for temporarily existing
