I think that's something many people miss: it can be desirable to declare the range of attributes on instances "up front" for optimisation purposes (in various languages other than Python), but the advantages of not risking the occasional AttributeError shouldn't be too readily discarded either. I'm not sure where the different tools stand on this front, but second-guessing invalid accesses to attributes is a completely different level to just identifying dodgy accesses to globals or locals, along with dubious imports and "bad practice" programming styles consisting of one or more of those more detectable things.
