I know this is malicious to those who want the web to be open, but I love it. Not because I particularly agree with the motive, but it's just such a cool demonstration of the power of React. Doing this has never been so easy. Google has been doing this for a while for a few of their products (Google Plus is one of them, I believe), but they've got large engineering teams who can commit time and resources to protecting data. If you have a justifiable business reason for doing this, then your life just got a little easier. I think this would also help against some forms of XSS too - so there's some silver lining for you.
