I think you've answered your own question as to why this hasn't been talked about: It's just another cop show. And it's being treated that way. The problem is "Lady Cops: Looking fine while fighting crime" very explicitely states that the show is about women. But if the predominance of female leads isn't advertised, then it wouldn't be that noticeable.
Perhaps you should see it as a good sign: it's nothing so outrageously rare and new anymore that people would be aflutter over it :3
