I think that the Yata mirror is kinda based on the user's own power and skill tbh.

Like, it has no weakness. It will block any attack, but maybe its extent is the user's power and/or skill with it. For example, Itachi can't stretch the shield to planetary sizes, but maybe Kaguya could if she had it.

Maybe the only reason the Yata mirror is so supposedly amazing is that it has no weakness. For example, Kakuzu could harden his body with Earth Release to be resistant to most normal techniques, but he was still weak to Lightning Release. The Yata mirror on the other hand will block any attack, but only up to what the user is actually capable of blocking with the technique. There are no advantages against the technique; in fact, it probably will be able to change its nature to counter the nature of any attack. So the attack's always at a disadvantage.

But attacks could still theoretically overpower it. Like, Naruto's Rasenshuriken would probably plow through Part 1 Sasuke's Goukyou with no problem, despite the Nature disadvantage. So maybe as long as the technique is more powerful than the shield's user, they can overpower the shield.

Keep in mind it'd have to be tremendous force. Like, Kakashi's Raikiri is an S-rank technique, but it would most certainly be reflected. Same with a Rasenshuriken probably, and that's beyond S ranked. Itachi has enough skill and power that the shield will be able to block them effectively.

But things like Madara's Tengai Shinsei? That shield is broken imo. Maybe Madara himself would be able to manipulate and strengthen the shield that far, but Itachi couldn't.

That's my take anyways. Also I think it's be silly to think Dan could get through the shield; his technique is a spiritual attack. He's gonna bounce off the shield.
