Logical things I think it could or should become the norm as well: electric razors, vaporisers, head-flashlights (like Petzl), many kinds of toys like RC cars and such, christmas lights, Halloween decorations etc etc.

It think in many cases it will usually be a lot more ecological to use devices you already own as long as you can and keep repairing them if possible. It’s nice to have usb-c, but throwing out a fine, still functioning toothbrush to replace it by a usb-c chargeable model just for that reason seems to me like the opposite of ecological.
