The only reason I think this could be stronger, is because the weak spot for HIC is normally in between the shim and the headset. In theory, this system eliminates that weak spot. After that, you would think the weak spot is right below the integrated compression ring, but the shim continues down until it's near the middle of the headtube, eliminating that weak spot as well (In theory).
However, a weak spot is created due to this system made to eliminate the weak spots. Since the shim continues down into the headtube, that creates counter leverage, so if you push the bars back, the shim will push forward and stop when it hits the headtube, creating counter-leverage which make it easier to snap. This brings the weak spot right back to in between the shim and the compression ring.
IN CONCLUSION, I think after a little bit the shim would crack right above the compression ring, allowing the fork to break soon after.
