For putting, Is angled hinging not superior to vertical in that there is now three dimensional impact and less associated clubface layback? Is vertical hinging not steering or a even a cut shot procedure? A reverse roll feeling?

There may be some associated green firmness considerations. Homer putted a well worn, fast and firm rug in his garage I think.

Correctly executed, all Hinge Actions -- Horizontal, Angled and Vertical -- are equally accurate. As you have suggested, there will be some distance considerations: Any Clubhead Layback will cause the Ball to travel a shorter distance with a given amount of Lag Pressure.

Regarding Three-Dimensional Impact, you are confusing the identities of two different Components; namely, the Inclined Plane (Clubshaft Control) and Hinge Action (Clubface Control). Each of the three Hinge Actions -- Clubface Closing Only, Closing with Layback and Layback Only -- can be (and ideally should be) executed on the Inclined Plane. In so doing, each Hinge Action is executed within a Three-Dimensional Clubhead Orbit: Downward (Attack Angle), Outward (Plane Angle) and Forward (Approach Angle) [2-C-0].

Alternatively, each of the three Hinge Actions can be executed in a Vertical Plane. This is accomplished by simply ignoring the Inclined Plane and covering the Line with the Clubhead. This removes the Outward component and produces a Two-Dimensional Motion (Downward and Forward). Obviously, this action can be accomplished only in the shortest shots.

And, yes, Vertical Hinging is Steering. However, done correctly and for a purpose, it is a valuable tool for the accomplished player. This controlled Steering is executed with a 'Reverse Roll' Feel (clockwise motion of the Left Hand through Impact, i.e., "holding off") and produces higher, softer shots (with Putts, less distance). Finally, as defined by The Golfing Machine, any stroke utilizing Vertical Hinge Action is labeled a Cut Shot (2-C-2).
