Well, maybe Artscroll is not allowed to teach them either.
The reasoning of the Prisha would apply even if she asked, until she proves that she can learn “?? ?????”.
I think this is what your quote from R’ Elyashiv says as well.
To summarize, I think we all agree that we can’t impose it upon them, which means Gemara class in elementary or high school would be out.
I think Sam and Simcha would say optional classes, say in college or seminary, would be okay, but I think any kind of encouragement is assur; it has to purely come from her. I don’t know what Patur would say about this.
Further, the way I read the Prisha, even if she asks, that is not enough to prove that she won’t be ????? ????? ????? ????; she has to actually learn by herself first, At that point, if she demonstrates that she was???? ???? ?? ?????, it would seem reasonable that a man could teach her further.
