[PyQt] Shouldn't an item view keep a reference to its associated model?

I thought it should be possible to have the views keep a reference to
their model without "owning" it, as you say. For instance:

  view1.setModel(model)

internally would do 'view1.model = model'

and similarly,

  view2.setModel(model)

internally would do 'view2.model = model', so that 'model' cannot get
garbage-collected as long as either 'view1' or 'view2' is alive.

What's wrong with this approach?

Thanks.
