The True Focus APL feature is useful when shooting something like a portrait in portrait orientation with a shallow DOF. So when you center focus on the eyes in the top 1/3 of the viewfinder and recompose, the eyes stay in focus.
In practice, even using a custom button access, I found that accessing the scroll AF points and setting the AF point with the A7R-II to take more time than implementing True Focus did. With TF, I needed to aim the center AF point on the critical focus area, then recompose that point anywhere in the frame composition. I didn't have to access anything and didn't have to scroll anything into place. Fundamentally, it is just the age old focus-recompose technique except the camera's CPU makes the focus adjustment.
Contrary to your opinion, I wish 35mm cameras had the True Focus option.
On the other hand, when you do set a focus point on a 35mm you can AF multiple times with the subject in that compositional position. So, YES ... it'd be great if MF could have a wide spread of cross type sensitive AF points to select from.
