What is this NoMa Neighborhood?

According to this map we saw right near the Ferry Building, it looks like the borders are Taylor, Bush, O'Farrell, and Van Ness, shrinking the Official Tenderloin to a mere twenty-ish square blocks. But wait...isn't Larkin Street now Little Saigon? How'd we miss the official renaming of NoMa? Is it going to have an incestuous relationship with NoPa? Would the kids be heroin-addicted H&M shoppers feasting on rotisserie chicken? The mind reels.
