This code is fairly independent of the rest, and we don't want net-device-wifi.c to become too massive and unmaintainable. The code in connection-editor/ is fairly similar to nm-connection-editor, with some simplification because we currently only edit wireless connections. The code in wireless-security/ is almost a straight copy of the same code in nm-connection-editor, with some changes to the .ui files to make them fit better in the new design.
