What is the advantage? To pay more?
I hear you, but to be fair it's the same TBN as MAG 1 10W30 full synthetic

Which is the same as SuperTech 10W30 full synthetic, and that did fine in this 6000 mile UOA (2019) from a 2008 KIA Sportage with a finishing TBN of 2.7

Notice how the add packages of Mag-1 SAE 30 and Mag-1 10W30 full synthetic look the same. That's because they probably are, as the package was probably developed as a matrix solution to multiple oils, as this is a more efficient development method.
I would have no problems going 6000 miles on Mag-1 SAE 30, and maybe more with a UOA along the way.
To what advantage ? Higher HTHS, Lower Noack and 100% shear stable as it's the polymer VII that shears, not the base oil.
