Some of the dangers to this approach include: the amount of memory allocated to the JVM. If you stuff alot of data into the Application scope, it persists in the JVM allocated memory and it's not available to the rest of the system/application.
You really can't change data in the Application scope without having to reload it. I generally use the Application scope for application wide CFC instantiation, the and not actual application wide data.
