DY- Dancing is a traditional way to celebrate the Torah. Dancing is a traditional way for women to celebrate things. Not every permutation needs to be played out.
In years past, most women didn’t really learn any Torah. They only connection to Torah was through supporting their husbands and it makes sense that their celebrating of Torah was through their husbands. Nowadays women are learning more and more Torah, their connection to Torah is not solely through their husband and it makes sense that some of them may want to celebrate in ways that aren’t solely through their husband. That doesn’t mean it’s not traditional. It was just never a situation that expressed itself in the past with most women not engaged in personal Talmud Torah as much.
Also, women who don’t support any men in learning Torah (like if they are single) probably aren’t “yotzei” by watching other men celebrate. It makes sense that they should have their own celebrations.
