No it's not. You are recommending the use of Network Manager instead of 
DHCPCD/WPA_Supplicant for headless Pi's, when it has serious problems 
which I and others have detailed. Your response is to suggest an 
increasing number of workarounds, some of which reduce useful functionality.

The reason the 2.4GHz SSID is configured is in case the Pi needs to be 
relocated to another part of the property where 5 GHz is too weak. This 
has never been a problem when using DHCPCD/WPA_Supplicant, so I'm not 
about to remove it in order to use a flaky Network Manager.

The sensible solution is to use the correct tool for the job, rather 
than whatever happens to be installed by default by Raspbian. This is an 
advantage of Linux, instead of being stuck with whatever Microsoft 
mandates you should use in Windows.
