There is a reason for USB-C extensions not to be part of the standard. They can be bothersome in the best case and dangerous in the worst.

The risk isn’t usually the device you connect a bad cable to (they have internal limiters), it’s the cable itself. You can easily overload a cable if the extension cord can’t signal the lower limit if it’s own rating and the other cable’s rating.
The USB 2 part is also misleading.
