I really have mixed emotions on this. It is clear the utilities are aluminum virtually 100% and they seem to be making it work.
I also lived with an aluminum house, my ex still has.
43 years later, she has had zero problems.
OTOH there are plenty of documented failures with binding screw terminal devices and aluminum wire so there is something going on there.
I do tend to agree, aluminum in an aluminum lug, should be fine.
