Containers being out of ISO 668 and weak was a risk that worried me for some time, but it turns out this is a risk for existing owner-operators too! Containers are inspected pretty regularly to make sure they're OK, or so our customers keep assuring me.
With that said, I'd really like to have some sort of load path-sensing autonomy onboard, like strain gauges in the corner posts of our sail which detect an incorrectly fastened or out-of-spec container before the other corners fail. Should be pretty detectably nonlinear if one twistlock isn't installed right and one corner post isn't transmitting any load.
