Benefits of running 2 Wi-Fi networks from the same router? What are the downsides? (I don't know if there is a better community for this question) (discuss.tchncs.de)

I am worried that there is not really a benefit of doing that, just more noise and energy consumption.

I remember reading a few self hosters describing having a separate WiFi for IoT devices, on a dedicated router (opensense) so they can prevent these devices "calling home". They are maybe other advantages like having different WiFi channels for these things

They can’t potentially send my “real” WiFi credentials to someone who might exploit them.
They can’t collect data on what is on my network or what I’m doing
If one somehow has malware, they can’t harm most of my network or devices (there are well known exploits for cameras, for example)
I can more easily limit the amount of bandwidth a poorly behaved device can use
