An added benefit is better engine cooling. The radiator would be slightly more efficient at cooling the coolant and the ATF cooler would also be removing some engine heat acquired through the exchanger.
Agreed. The oil does run hotter but a filter base O2O exchanger is small (only slightly larger than the filter diameter). The amount of heat transferred is limited but effective.
