Your are right, the flex happens in the arms, but the yield point is at the back where the arms are welded to the vertical portion. Most that build their own frame do it with thicker material to limit the flex and allow the hydraulic front end to do the most work. However the welds at the innermost point are right at the theoretical yield strength, so done correctly, this can be strengthened when constructing.
