in addition it is explicit allowed to roam between WPA and WPA2
networks. So any distinction between these two would be a bad idea.

Actually this should work, however if you change the security on your AP
from lets say WPA to WEP, then it becomes a new service. So we can not
tell you that the service has changed. You will see a service going away
and a new coming. For changes from WPA to WPA2 you will see nothing
since for us they are not different anyway.
