Some images of the plugs, since I didn’t know what they looked like.
It was mentioned the pins started being insulated like that second image 20 years ago, but going by the images I found the older uninsulated style is still more common. This is ofc a major shock hazard when plugging in your stuff.
Even with the insulation, you can still reach under the half inserted plug, just less easily and maybe only if you have smaller hands (like children).
Fundamentally flat sockets are doomed to be shock hazards, compare it to the recessed sockets where the entire surface the contacts insert into is cut off from reach before the pin insertion starts, and on top of that the pins of say type F have been insulated for so long many don’t know there were uninsulated variants.
Another bonus of the recessed style is the plug doesn’t stick as far out of your walls. For extension cords it’s probably a bit bulkier, but when you sink the recession into the wallbox of the outlet you can get as flush as the width of the cable with an angled plug.
Also pretty sure you can step on angled type I plugs resting on their backs. The recessed plugs usually have grips on top so can’t rest on their back even when angled. Their pins are also ball-shaped on the end, type I looks quite angular and more painful.
Oof, I see.
Kinda a bad look for type I when some of the users follow a different spec and ruin all attempts at improving safety or even keeping standards like earth being down.
In comparison the european plugs are moving closer together, for example F+E combo plugs are increasingly common.
