Heh, not exactly. We have a finite amount of hours in the day, and maintaining a JSX implementation is something we just aren't really interested in. You're more than welcome to implement such a thing yourself though, and I'd be the first to retweet it if you did.
I proposed the idea of using JSX as angular2 templates. They didn't like it and I think the React competition was an important factor for that.
