It' looks to me like ".home", ".corp", and ".mail" were reserved as "high-risk", and then they refused to approve any of them as gTLDs.
I see an argument that ".dev" should have been considered "high-risk", but it doesn't seem to have been on the list. So this isn't a reason to distrust ICANN when they say they won't be approving ".home", ".corp", and ".mail".
