My mentors used to say that there are only two times to avoid a sharp dogleg......one is where there are trees, and the other is where when there aren't.
I did find one good use for a near 90 degree dogleg. If there is a pond the length of the driving zone, and a wide fw, playing safely costs you 30 yards on the approach, and I never put a hazard on the other side, just to keep them honest, as encouraging the safe play caused more penalty.
My mentors had designed a 90 degree dogleg with a pond just at the LZ. It turned out it was shorter to lay up in the rough as the distance to the green was the same as chancing the pond with a full drive, which highlighted their point of view.
