IPXX rated usb c connectors are on phones everywhere. Li ion button style cells are cheap and easy to implement. You don't even need a connector with inductive charging. It's not like the technology isn't mature.
Coin cells are in key fobs because many cars charge them. I haven't changed them in my keys after 13 years. You'll see them disappearing in coming years though.
Responsible users will of course dispose of them properly, but we all know it's not a world full of angels.
