Re: New Star Trek TV Series in 2017!
Meh. That canon has been screwy from the beginning. The very first episode of Trek ("The Cage") had a female first officer, who was put in command when Pike was captured. Depending on which Trek you follow, there's an argument that that, in itself, makes her the first female captain (there's a line early on in "Enterprise" where Travis says being put in command makes you a captain; basically the entire plot of Trek '09's rank craziness confirms this).
There was a female captain in Star Trek IV, so by about 15 years later (-ish) it wasn't a thing, anyway.
Erika Hernandez was the captain of the NX-02 in "Enterprise" looooong before that episode, too - some people explain that away in that Columbia wasn't a Federation starship, only an Earth starship. But come on. Seriously?
The only way that line really makes sense in light of all that is that there wasn't a female starship captain at that moment in time. And considering (depending, again, on how you read canon and TOS' very loose dealing with it back then) there were only 13 starships at the time ANYWAY, and a few of those had been destroyed or lost (The Defiant, the Intrepid, the Constitution), it's not all that surprising that there just wouldn't have been. NOT that there COULDN'T have been, just that there wasn't at that moment (Or, that there was some really conservative upper echelon in power that was sexist at that time...ahem).
So, point is...it's a moot point. You can canon away anything.
Personally, I'm meh on everything thus far - the ship design, the uniforms, the casting - except for Doug Jones. Always loved him. Michele Yeoh - in the one movie I've seen her in, Tomorrow Never Dies - was downright horrible. So we'll see.
