I wasn't aware that there is this kind of limitation in the D-Bus
interface. It is clearly broken if it cannot include both of those
networks.

I don't know how this mechanism is supposed to be used, but there needs
to be a way for fetching more information about the BSS and BSSID by
itself is not a sufficient key for identifying which BSS is being
queried for (need to have BSSID,SSID pair or some other internally
generated identifier which can be guaranteed to be unique).
