I don't mind having a harder difficulty to unlock so long as this is done with purpose beyond just giving us one more thing to do. It's important that mindful developers be able to dictate the level of challenge presented by an experience, as they can use this to great effect in accomplishing their goals. Carefully controlled difficulty can be used to enhance a story and better immerse players, while an extra-hard mode might provide an entirely different, less-desired experience for the first playthrough. What we need to recognize is that the rewarding feeling we get from overcoming the steepest challenge a game can throw at us is not the only reward we can receive from playing games. If a developer wants their players to first experience a more "normal" difficulty because they feel it better suits the atmosphere and story they're trying to convey, but also wants to accommodate players who desire the satisfaction of beating that higher difficulty, they may see great value in having a harder setting unlock after the player has first experienced the game as the developer intends them to.
All too often, this aspect of game design IS ignored, I'll grant you that, and in those cases it's very annoying, but careful control of the difficulty settings first available to players can be used to enhance the experience. It's a tool I'd like to see developers utilize more frequently.
