Ask HN: Rip out Twitter integration that uses find friends functionality?

I'm about a week away from launching a project that depends pretty heavily on the social graph and your connections in it.

I have both facebook and twitter authentication, and for each the app hits the relevant APIs to find your friends who are also using my app.

I've definitely focused more on twitter integration, as I view the twitter identity as more lightweight and less invasive- given the choice I would always sign up for services with twitter over facebook.

But at this point, I'm seriously considering ripping twitter auth out entirely given their actions the past couple weeks with turning off the find friends functionality on tumblr and instagram.

I realize it's a huge longshot my app gets to the size of a tumblr or instagram, but the whole thing is pretty much predicated on the apps ability to connect you with your friends.

So, HN, would you remove 'find friends through twitter' functionality from an app before launch, or would you go forth with it and wait for twitter to shut you down? Is it a real concern that I may lose this functionality? Or do you see that as a great problem to have, i.e. got enough traction that twitter noticed?
