It seems to me like the desire to stick with moa is that it's easier to do things the hard way with moa. There's no need for converting mils to or from inches, so the difficulty in converting is not necessary. This is all predicated on having a reticle that you can measure with of course, so with simple duplex reticles I can see why people don't care or want to stick with moa.Shoot, measure with reticle, adjust. It’s just that simple, mils or moa.
