@BeAware It might, I guess (where'd one's data be stored? Locally on one's devices? That also can be dangerous. Distributed throughout the whole network? Hm... I dunno...), but I also suppose that you'd have a much harder time approving and then implementing something that changes stuff at the core of the whole shebang than just building a new service on top of what's working now.
Then again, that's me talking off of my derrière. I don't know nearly enough about all this to have solid opinions.
