Because that is the "contract" between the flowscript and the 
presentation layer.

Because when using the flow you maintain the application state in 
JavaScript program variables.

Not sure what you mean here. Can you explain?

That's not the case. All are equally crippled ;) For example, when using 
  Xsp, the idea is that the only logic sheet you will ever use is the 
jpath logic sheet. This does not give you direct access to session, 
request, or context but only to the bean object. Likewise with XMLForm, 
you only have access to the bean itself.

Hope I'm answering some of them :)
