Thanks for clarifying. I think this is no 'should'. At least, to me, this was one of the main disadvantages of Marionette, that it forces you to make very small views, even if there's no real reason (I think this example is a good example of that as well). I'd be all for a solution where it isn't needed, but for now I think the performance change could be drastic for current users of the library, so I don't think it's something we should change.
