The implementation doesn't matter -- this is a spec issue. For example,
let's say you're rendering an input control in response to an Ajax request.
Only the value property has changed. Right now, JSF will re-render the
entire component, including all of its markup, and then replace that
element in the browser's DOM. Instead, we could send JSON with the single
property, and the component could update itself based on that property. (Or
JSF could handle components in a standard way but allow components to
override that behavior or opt-out altogether.) For more complex components
(and this includes CSS-based input widgets that replace the standard JSF
input controls), the result is decreased bandwidth consumption and more
responsive UI changes.
