Ok now that's actually legitimate reasoning. The intricate mechanics of how the shield actually alters its attirbutes are ambiguous, but kishimoto doesn't have to subscribe to those in the fandom who want a strict scientific explanation, its a manga for entertainment. And yea, Kishimoto is a bad writer for jot taking that extra step. I addressed the nagato incident before, two things: plot, wnd it wasnt necessary for what was needed. It's the same reason itachi used amaterasu on nagato instead of just sealing him with the totsuka blade, it's all to drag out the battle. Even if the shield creates an anti gravitate force, that just renders him station ary and he has naruto and bee to worry about as well as taking out nagato. Destroying the core was the more proactive choice as it stops the attack actively and created a huge smoke screen to catch nagato off guard. The shield can change any of its properties but it only does so for the attack at hand, meaning the shield is sentient, commanded by itachi,  or some combination of both much like gaara's sand. In either case, the yata mirror wasn't used because itachi was using a lower stage of susanoo, so he felt it wasn't necessary and he was right. Why the shield wasnt used again? Plot and bad writing. But that doesn't automatically make it a reason to ignore in vs battles, because as far as we concerned it theoretically doesn't have  a known limit. So yea, it does bring an issue of logistics, but that's about it, so we have to go by what we have. So it's best to assume that as long as itachi's stamina holds, nothing is getting through that shield. The only possibility is underground attacks at itachi's feet probably.
