Detailed Wi-Fi menu by default
This is quite a workaround to go through and unfortunately involves paying for a software (unless you're aware of free alternatives)  but thought I'd throw it out there while looking for more details:

Using a program like Keyboard Maestro, you can record a Macro that will be the result of a string/hotkey. 

I recorded as follows:


Hit record
Pressed and held option key.
Clicked on Wifi menubar
Stopped recording.


I then set up the trigger to be a hotkey (like CMD+,) or a string like wifio. Both worked. Detailed Wifi menu was opened and waited for my choice.
