Tuya Binding setup

I just set up my first Tuya Wifi device and experienced some difficulties during the initial setup of the OpenHAB core Tuya Binding, mainly due to being too impatient to read the instructions, but in any case they are tedious.

On a HomeAssistant forum I read that they switched to a new setup method two years ago, which allows for just scanning a QR code and skips the need for a developer account at Tuya:

(The forum entry which led me to this was Tuya Issue - Switch works in Smart Life App but shows offline at https://iot.tuya.com/ - Home Assistant Community)

Now I wonder whether that method has any drawbacks compared to the “old” one that OpenHAB uses, or whether implementing it could be worth a try. Has anyone already checked that out or any idea or opinion on that topic?
