I don't think that would be needed. We currently use the same approach as maven, and have a "permanent" cache for artifacts. There is a difference between the JavaFX libraries and application-specific components. The JavaFX jars are not linked to a specific application, but can be used by a number of applications (at build time as well as at runtime). 
I agree that application-specific components need to be removed (when possible) from the user's storage, but that is at runtime, and only when these components are only used by the specific application.
