Thanks, so I'm wondering why would we want to make an effort and let
users write

'public Response<List<Bean>>'

What is a List<Bean> on the wire ? It can not be properly described.
That of course can work, we can even customize easily the wrapper name,
etc, but I'm not sure it's a spec level issue at all

Cheers, Sergey
