The problem with using non compliant stuff comes in when you perhaps lend the car to someone and they dont know its only a bike rack and hook a trailer full of gravel on the thing.
It rips out ,hits a car and kills someone.
A how would you feel and B could your pocket stand the cost if they sue you. Also if you sell it and the buyer thinks its a full towbar.
The bracket may look strong enough but with the twisting forces exerted by a load on it may well cause the panel it is fitted to to fail.
Put a proper towbar on it and be safe.
I have seen bikes lying on the road along with inadequate mountings after having been subjected to bad roads.
When you hit a bump an engineer estimated that the load becomes up to 7 times its static weight
Something to consider
