Are Layers still necessary in 3.0?

Now that touch events are handled by EventListeners, rather than special Layer methods, is it necessary to use the Layer class any more (besides backwards compatibility with older code)? As a test, I changed my HelloWorld object to be a subclass of Node instead of Layer in my v3.0 project, and it seemed to work OK.

Is there something else I might be missing?

Not sure the future planning of cocos2d-x but I think we could now be able to compare with others.
For general User Interface, you may review the usage between “Control” and “Panel”/“Layer”

I think layers can be replaced with just nodes, lets see how it pans out, we might deprecate layers in the future

:;qst cocos2dx become more and more strange! I think layer is useless too!
