I didn't even notice. I don't pay attention to these things.
IN answer to your question: No. Not necessarily. It's most of all a sign that these women are making good films, and jurors are trying to reward them.

I've been writing about Claire Denis, certainly one of my all-time fovorite directors, who is definitely a woman.

Also one of my all time favorite writers is a woman, Jane Austen, and one of the greatest novels in English of all time is Middlemarch, by George Eliot, a woman.

But n the plastic arts, in painting, women don't matter very much to me. And in classical music or jazz, not so many women stand out. Exceptions: Martha Argerich (big one) and Marin Alsop (pioneer woman director: I've reviewed the documentary about her. And she was the BSO conductor - Baltimore, my home town!)
