Would it be feasible to let properties return some kind of "Undefined" or "NotImplemented" or "None", rather than throwing an exception? But generally, - I am -1 to deprecate properties in general (here I include lazy attributes, which I find handy). - I am +1 to introduce the policy that properties should never throw exceptions (and thus to deprecate all properties that currently do throw exceptions).
