I think the risk of this possibly happening at some point in the future is a relatively small price to pay in order to encourage uptake of zero-emission private transport.
Public chargers cost ~56p/kWh; overnight home charging on a smart tariff is ~7.5p/kWh. Enable those living in cities without driveways to take advantage of this and cut localised particulate/NOx emissions. No-brainer.
When they are new and maintained, sure. When they are a few years old, have got clogged up with dirt, the user doesn't bother to clean it out and the cable is now above the pavement level.
Those pictures also feature level paving which is far from the norm in much of the world.
