That’s true, but it’s also important to clarify that if I understand it correctly, using Shizuku or wireless debugger mode is specifically dangerous on unknown networks, like public WiFi networks, where anyone could connect to your device with adb, but in case of use from a secure network such as your home (unless some device has been infected by some type of remote control virus) you can use it without problem.
I understand that most people will not mind leaving it on and their phone will automatically connect to any WiFi network, but in my case my device asks me every time I start the wireless debugger mode that if the network I’m connected is a secure network, and it only works if it’s connected to this network.
