Well... I'd sure like to live in a world where users thought about the
implications and risks of what they're using and why, rather than
farming a decision out to a static analysis tool. ("And as long as I'm
dreaming, I'd like a pony.")

But end users already control the initiation of OAuth requests (it's
opt-in via the connection string), so that's not really the goal.

Awesome. I think we have a consensus.

Thanks!
