Once a hardware interlock safeguard requirement is put in place by a regulatory body it’s rarely removed. See British fused sockets for instance.

My threat model allows me to be completely cavalier with a dishwasher. I would be considerably more serious with safety concerns were I to put a chemo machine in my garage. My suspicion is that people who haven’t shipped home appliances connected to mains are not aware of how much of the engineering effort goes into making these machines safe relatively to how little it does for adjacent categories and are mis-indexing risk over bigger issues like vendor lock in as with the Sonos upgrade fiasco a few years back.
