I am careful to not complain when there is the possibility that bags are mixed and I do not expect 100% of the bags on the baggage claim to be SP as I understand that you need to stack luggage logically and sometimes it is more expeditious to intermix bags to reduce total wait time at baggage claim. However I am witnessing a change where SP is being ignored quite often. I have even taken to filming the bags coming onto the carousel to validate my claims to Delta (so they cannot claim intermixed flights,...)
