Yes, the 1050 has no vertical stabiliser, only a rudder. You can see it pretty well in the picture on Wikipedia.
That’s a matter of definition, I guess. I would certainly call that a vertical stabiliser even the whole thing can move — just as I would say that a Cherokee has a horizontal stabiliser even though the entire thing also serves as elevator.
I read somewhere that while skin drag is the same (same total wetted tail area as a normal 3-surface tail), the speed advantage comes from slightly lower interference drag due to fewer joins between the surfaces and the empennage.
Then everything else isn’t equal, and the conventional aircraft has better (higher) stability margins due to the added drag. This can in turn be “fixed” by decreasing the tail area of the conventional design, or increasing the area of the V-tail.
That’s a matter of definition, I guess.
Correct, and it has been defined already. No need to change. Same with the all flying elevator of the Archer. If you’re not using terms correctly, you won’t be understood.

Of course it is exactly that, functionally. The plane would be out of control within seconds without it.

I’m always pepared to learn more. Please point me to this definition.
I note that the Oxford Aviation Academy’s ATPL manual states: “The vertical surface(s), vertical stabiliser or fin, generate sideways forces as required.”

A very loud Fouga Magister was seen doing some flying at my base this weekend 
Wish I’d got a photo of it in the break, it’s very elegant with long wing and V-tail, whistling on closed throttle at high angle of bank. All I got was a little phone video, from which I extracted this photo of the takeoff roll.
The initial angle of climb, like other trainer jets of its era, was visibly horrible. Hope the neighbors enjoyed the noise on the upwind!
Probably a “hey this looks fast” fashion during a particular era
I remember seeing 4 Magisters parked at Gallway in the early 90s. The Irish Air Corps used them.
