I'm not a great fan of USB-C ports and cables. I have an Android phone with a USB-C that only accepts charging cables when inserted one way. When a USB-C cable is plugged in if charging doesn't start then I turn the cable over and charging always starts. This holds for multiple cables, three of four, so the defect is in the phone. The phone is not a beater. Thought the phone is older it has been well cared for. The USB-C port is simply worn out.
I haven't yet damaged an USB-C port but that's probably because I rarely use it. Most of the USB ports on my computers are USB-A, and USB-C ports are still the exception rather than the norm. However, over time this may be changing.
I think charging batteries in large cameras via the camera is not a good idea because frequent use of the port will eventually damage it and over time the camera becomes unserviceable before the end of its otherwise useful life. I prefer taking out the battery and charging it separately because then if I drop something it'll only be the charger and battery, not the (expensive) camera.
I think the EU is simply assuming that all portable devices are short-lived and disposable and somehow the chargers have become the source of environmental damage - which is curious, as I'd think the short life of the phones and other devices would be more of a problem. With dedicated cameras, the expected lifetime of the camera is much longer than that of the USB-C connector and so while it can be convenient for some situations, the separate battery chargers should continue to be available. I hope that the chargers don't become so rare that Nikon stops manufacturing them. That would probably mean a camera's lifetime is reduced, and there may be more pollution in the end.
Off the topic some: I believe the Apple Lighting Port is more robust.
Be that as it may, it's going to be history.
I've found Apples lighting charging cables to be quite short-lived and I periodically have to buy new cables. Hopefully the USB-C cables for future iPhones will be more rugged.
