No, it's just there to make you more comfortable with what you're used to. Have you ever had a pillow and it's an awesome pillow and it's covered in your warm love and hair and head filth and you sleep with it and your life is the best (especially when you flip it and it's cold, god yes)
Well, have you ever gone to a hotel and not had that pillow? You feel empty inside and you feel that bad people will take you away in the night because your kickass pillow isn't there.
That's what this is like. Just making it more comfortable for new comers. It's such a small feature to those that will use D, F anyway, I don't see where any problem would come from. Now if you'll excuse me, I'm going to go tell my pillow I love it.
