The method doesn't need the self(instance) or cls(class reference) therefore by definition it's a static method, so when I implemented that I didn't intend to create a function to be used in multiple places it's just a static method that could be used in other context

Why you change to obj if in other places is agregator.

I understand your concern and IMO it's much better aggregator however your argument is not valid since in other places is obj

event = "progress" if obj.percent < 1 else "completion"
event_type = obj.aggregation_name

That method just validates the kind of event (progress or completion) the data that is sent must be as accurate as possible
