My biggest concern would be children doing what they're not supposed to.
The grotesqueness aside, I do loath the pendulum swing we have toward safety these days. It's so bad now that it makes things worse in a lot of cases. I have to dick with my phone for navigation (which requires a lot more looking away and danger) because my car won't let press a couple of buttons while it is moving in the name of "safety."
It's actually quite astonishing how, despite the growing chemical and mechanical complexity of household items, most household things are actually quite safe to have around children. It would be quite easy for these things to be actively dangerous, but fortunately a combination of thoughtful design, fear of lawsuits and regulation works to make them safe.
(Also if we're talking in context of white goods, you can't ignore children in the design process, as a good chunk of the target market has them, and the play around where such appliances are deployed.)
Example of mindless nanny-statism: washing machines that you are simply not permitted to open at certain times, period -- not even in case of power outages, component failures, or plumbing emergencies.
I hope you can see the difference. Don't defend shitty engineering. It makes the whole world a worse place to live.
