that was on a stroker, and I'm not sure if that engine used a stock oilpan or not, but on a stock oilpan, there is a tube welded to the inside, where the dipstick goes into which should make it impossible for the dipstick to get chewed up like that one did
however, you do make a good point on the dipstick tube being a weak point, and needing inspection
you would not want it to crack there and leak, or become loose and leak
