REALLY WOULD LIKE NIKON TO SUPPLY A SPLIT-IMAGE FOCUS SCREEN FOR D800 et al.

Am I the only photographer who misses the control and versatility of using a split-image RFR and manual lenses for my critical work? Yes, I know that third party vendors supply their own solutions (I bought one for an earlier DSLR and the focus was never quite right. A Nikon repair station charged me $100 to tell me that the screen was not machined correctly. Nikon could easily design and offer a factory specs screen. Is there anyone else out there who could use one?
