 So these work the same way that air line fittings work? If so it's about time!

I'd seen them in race cars for brake lines mainly .  .  . and fuel

There's a slightly different variant that's been out for years I used on my Aprilia RS250 racebike. It let me switch the front brakes between two different systems without taking off the bodywork. After 3rd or 4th time, they need to be bled, but totally kicks ass.
