I think that RfA might be a good idea, except that Rollback isn't that much of an upgrade from normal user. However, since a Rollback would be in a position that could allow them to do major damage, perhaps a smaller RfA (RfR, I suppose) would be good, and needed. On another note though, if this was just given to users who needed it and deserved it, then there would not be much of a problem.
