There are non ash detergents in the oil. Molakule has said somewhere that calcium and magnesium are secondary detergents. I don't know how long that's been the case.
The same thing goes for new HD diesel oils with lower ZDDP. They didn't just lower the ZDDP, they're using stuff we can't see in UOAs to enhance the formulas.
Time will tell I guess, but I think all of these new oils are going to get the job done just fine. I'm putting my faith in low ZDDP HDDEO already and I will be using the new PCMOs (Dexos gen 2) without a worry.
