It should be just easy to use your offline debian-11 vault to save the
wifi passwords and insert it once you connect to a particular wifi.
There is of course an advantage for your anti tracking setup (together
with other ones). So in this case if your sys-net gets compromised
(unlikely but still possible), an adversary could see all your stored
wifi connections which can give him unneeded advantage. This doesnt
happen with disp sys-net.
The question is: What makes you more happy? Connect to the wifi
handsfree and possibly give out your wifi history intelligence to an
unknown parties, or you are more happy to insert the password from the
offline vault manually and be more safe?
