They are like Contra 3s or many other retro games. There is a difficulty in adapting and conquering the controls. I was recently playing the indie game RIVE which has twin-stick controls as you describe. It does make it a different game though. Like letting Mega Man shoot diagonally.
You could argue controls should empower the user as much as possible as long as it isn't playing the game for you, as with auto aim, but learning how to adapt to limited controls is a legit aspect of difficulty to my mind.
