Adam,
Leaving aside any issues around the manufacturer’s installation instructions…
What are you suggesting as an alternative to stabilize the window at the sill? The back-dam will stop any movement inwards, but you need something beyond relying on the inherent strength of the window extrusion to stop any movement to the exterior. Solve that and practically you can eliminate the straps.
The last time this came up the OP suggested attaching L brackets to the rough-sill, and screwing them into the window frame.

Unless the window is directly against the backdam (as a mechanical stop), what’s the problem with putting a bent jog in the straps?
