Includes aren't strictly necessary in XAML or MXML because both of those are compiled to classes
that can then be referred to directly as elements. For example, if I create MyClass.mxml,
I can then use <MyClass> in another MXML file. Since BXML is not compiled, we use includes
to achieve the same type of behavior.

To your other point - bind() isn't meant to be a means for initializing all possible member
variables. BXML's primary means of initializing member variables is via elements and attributes
(i.e. bean setter methods). Binding is simply a convenience for mapping variables defined
in BXML (either with bxml:id or in script) to internal member variables that you don't necessarily
want to expose via a bean property. And of course you can always perform additional initialization
in your class constructor itself.
