They do -- I carry one one of my employees made in our lab. Search for "usb-c condom" or "usb-c data blocker" and you will find several offered for sale.

The ones I've seen work by severing all of the data pins, limiting you to the old 5 V * 2 A limit. Have you seen any data blockeds that support the power delivery spec and are suitable for devices that need over 10 W (larger laptops, the Switch, etc.)?

I have one that negotiates power delivery on both ends. But I don’t believe it was manufactured commercially — it’s just a bare board with no housing. I’ll ask the guy who made it if he’d publish the design files.
