I would prefer if wpa_supplicant gets a global method for setting the
alpha2 value. It should be dynamic and for me wpa_supplicant is the
right place to handle this value.

The question on how we set this value is a little bit more trickier.
What we do need is a Location Manager that can use multiple source to
get our current location (WiFi, GSM/UMTS, GPS etc.).
