I think that's not quite right. In fact, your Android device will still send home the _nomap SSID and its MAC address to Google, specifically so that Google can remove the MAC from its geolocation database (where it's almost certainly already collected). This will make it harder to test, and require us to trust that these geolocation providers will remove any previously collected data, but enables retroactive opting out, which is essential here. It will be difficult for an owner of an access point to confirm that her access point has been removed from any single geolocation database. To represent current practice, I think you may wish to add an exception to draft-hoehrmann-nomap to allow the communication of the SSID to signal removal of information about the network from collected databases. —Nick
