Definitely the norm in India. Where AI, 6E, etc. when bussed (sometimes, for what seems like basically forever, esp. in BOM) to the plane on the tarmac, boarding is done through both front and back doors. 6E even has messaging in the buses and on the ramps or stairs (yes, they use ramps, usually), saying which rows should board through the front doors and which through the back (IIRC, rows 1 - 15 in the front, 16+ in the back, but its easy for them since they operate only 320s).
