No thanks. Flown NVG HUD many times and it’s annoying. The information blocks too much of the viewing area and doesn’t need to be displayed constantly anyway.
They’re grossly exaggerating the amount of time to glance in the cockpit and interpret the instrumentation. They make it sound like its task overload or something. You’re flying VFR, the primary purpose should be to enjoy the view, not flying like a robot focused on goggle symbology. Also, you’re still going to have to glance into the cockpit to get your engine instruments.
