Here it makes sense to use generation/version check since we need to ask questions to users so it's harder to do feature detection.

Control requests prevents the user to pre-configure the wifi if the SSID is not present on the area.
The use case that made us to rollback the first change was:
On production line some costumers requires to pre-configure the wifi credentials the devices will use in the work area. (the devices for this use case were P2/Photon2)

Good call Hugo. Keerthy changed the fix to use control requests for DVOS >6 (since serial commands are gone there) and she'll figure out with Scott a better solution.
