None of them have since the original 3DS, not even the regular 3DS XL (except 2DS of course).
Numb hands sounds about right, but it's worse when you're playing one of the 3D Zeldas, doing a boss battle and hammering the face buttons whilst holding L to lock-on. Link Between Worlds hasn't been an issue for me.
Oh yeah. Now I remember, it wasn't too much of an issue though when you mastered it. Still worth it though.
