I would appreciate some documentation on motivations in JavaFX 
architectural choices.

By example, here is my biggest question: JavaFX has mostly a retained 
scenegraph, but use immediate events by defining immediately-called 
listeners on each property. How not using retained listeners per 
control, called only at the end of an operation-transaction on the 
control (as defined by Platform.runLater) or even a global event bus for 
retained events of the full scenegraph?

If event-handling is not part of properties, controls would be simple 
Java beans using standard Java classes, and not use the specific 
JavaFX-observable classes Observable*, *Properties, etc. (this can 
possibly reduce static and dynamic footprint, if cost of control-scoped 
listeners or global event bus is sufficiently small).
