Ah you're right. First I've heard of USB 3.2, but here's news from 2017: https://www.anandtech.com/show/11667/usb32-update

I have a USB-C drive enclosure, but looking at the specs it's only USB 3.1. Newegg doesn't even have 3.2 as an option when searching by external interface in their hard drive enclosures section. The day when you're actually losing anything by not having USB-C devices seems a ways off still.
