"A decision on who the woman will be won't be made for several months."
I think it's pretty gimmicky and stuffty to choose the gender of the person before the person themselves.
I'm in complete agreement.
Pick a meritable person to put on the bill, and then do it. We'll notice that it's a woman.
Announcing they're planning to put a woman on it but not knowing who it will be turns it into a pandering token gesture.
