This change should not break usage with passport 0.5.x since the callback was not needed in that version and just wont be used.

This change should not break usage with passport 0.5.x since the callback was not needed in that version and just wont be used.

I agree, but the types will break. We actually should probably update the types to indicate that the callback is optional. Are you interested in doing that?

Also, things will behave differently since now there is an async callback. So our code necessarily has to be different.

I pushed some commits to reduce code duplication and make things easier to read. If you approve of these changes, please post a comment and then we'll get this landed.
