When will Nikon design lens for Dx as a system?

How weird is that they don't design any specific lens to align with typical FF equivalents? Where as Mirrorless have focused their designs to align with FF eg 28mm (14mm) 12mm (24mm) etc, Dx makes do with cast-off FF designs!

Well its no wonder if things are going a bit flat when Dx seems to be making do, about time Nikon realised people will never ever want or need to carry around FF and that size lens, what was the reason for Dx if they dont follow through with proper designs.
