Cellular Data for iCloud Backup

I think it is about time iCloud Backup should be extended to enable Cellular Data be enabled for it's data Use. My Understanding has been those from Africa and other less highly technological places have had it difficult in backing up their phones on iCloud due to the exclusive request for Wi-Fi. At these places Cellular data is mostly the source of readily source for for all internet connectivity's. So I think there should be a conscious effort to allow iCloud Backups through Cellular Data.
