>if the existing "iw" command is no longer valid, quite a bit of documentation will need changing!

"iw" itself is not in the crda package.
However the script that reads and applies /etc/default/crda do is.

So perhaps just let netplan set country code in wpa_supplicant.conf and don't bother with /etc/default/crda ?!
