Summary from company chat:

• Attribute names might be long and chained attribute call will turn into a long string. It rarely means something good if you climb through several “dots” in expression.
• Django ORM is a different story and requires separate note
• Rule was written before PEP-678. Try to figure out the error if an exception is thrown in such a chain foo.bar.bar.bar.bar.bar.bar.bar (nonetype object has no attribute bar)
