If studying the history of music, I think it would be reasonable to look at how different groups of composers wrote, shared, and popularised their work. Was the style very different as a result? Was the format different? Did it influence other, better-known composers? I'm not a music or a history buff, but if the way women worked was significantly different to men, then it makes sense (to me) to include that in a course to give students a broader understanding.
Further, if such different compositional movements merged, then that could be interesting to study - how did it happen? What sparked it? Or if they are still separate, why is that? Is it a deliberate separation?
Perhaps it is a political agenda, perhaps it's not, but without seeing the curriculum itself, its intended purpose and an explanation of why there are only female composers, I think it would be prudent for me to reserve judgement.
