So this exit node is censored by Turkey. That means any site blocked in Turkey is blocked on the exit. What about an exit node in China or Syria or Iraq? They censor, should exits there be allowed? I don't think they should. Make them relay only, (and yes that means no Guard or HSDir flags too) situation A could happen. The odds might not be in your favor. Don't risk that!
Where do you put the limit?
Various categories of websites are blocked in various countries either by ISPs or by content providers.
