Home electrical load safety is based on distribution being a tree, with a breaker for each branch. The branch breaker will trip if there's an overload on that branch. Outlet strips with their own circuit breakers are sub-branches. This is all worked out in the US under the National Electrical Code, so that you can't overload a branch circuit without tripping a breaker. The UK uses BS 7671, which has the same goals but different topology. Residential users don't have to do load calculations or make measurements. This thing breaks the simplified rules that make home electrical safety work. The obvious way to get into trouble with this is to plug in two of them on a circuit with heavy loads. Now you have a big source and a big load without a breaker between them. Germany gets this, and requires that a licensed electrician add up the loads, check the topology, and do the install. One way to make this work safely would be to require a special symmetrical connector, with both sides protected against touch. That has to be on its own branch circuit, with a breaker between it and any loads. That becomes a legit place to plug in source devices. This is essentially the same as having a dryer or A/C outlet installed.
