Yes, I agree somewhat. But, it does make sense to have a weak link to protect the structure. The problem came because the builder put the bolts in with red locktite I believe. Or else they put nothing on the threads and over 10 years they managed to weld themselves in there. The broken parts were stuck in there solid. The new ones I put in are liberally lubricated with anti seize. So, hopefully if they break again I'll have no trouble removing the broken bits. And, if they don't come out it shouldn't be too hard to unscrew the new plates and get a vise grip on the back side and spin it out. I might even take the bolts out every couple of years and re-lube, if I remember to that is.
