https://news.ycombinator.com/item?id=50070844 : UKGOV has gone for the warning notice solution.

I think this is probably fine, since UK circuits are typically 20A. Apart from fault current (which would have to be line to line, since line to ground would trip the RCD), it's quite hard to end up with more than 20A of stuff plugged into regular sockets unless you're overinvested in portable heaters. All the big stuff - cookers, heat pumps, showers - is on separate breakers from the sockets.
