Generally I would agree with you, but I have not seen Ford develope a "specific" oil for no reason. Usually their oils have some spec and the manual would state you should use an oil that meets their minimum spec, for the "disconnect" PTU and RDU used on 2019+ Edges, I don't recall reading the same.
In the link for for redline MT-LV specs you posted, it is clearly stated:
MT-LV, MTL, MT-85 & MT-90 are not for use in differentials with hypoid gears
Additionally, the OEM compatibility does not include Ford's disconnect oil.
