This feels like something that's "security by obscurity" vs. "security by obscurity." Would you rather be obscure because you have the same SSID as everyone else so no one guesses which is yours or obscure because you have the same SSID as everyone else and no one knows which is yours, but it's easier to see what is going on inside the network?

One comes with more easily identifying you/your network while the other comes with being more easily hacked by readily available rainbow tables (I think, but am not sure, that WPA3 fixed this, but WPA1/WPA2 use the SSID as a salt for the password)
