Not realistic wont be implemented, it was made quite clear in many FAQ's and suggestions threads. As for the gameplay itself there's always a way to implement it without breaking realism. Why would you even want one on the other side of the road anyways? Is this some why did the paratrooper cross the road joke I fail to understand?
One of the possible reasons I can think of is to make the attackers more spread out on a wider spawn area in case the deffenders make a hard push back.
Optionally there can be just a little "regroup" area on the other side of the road in case **** hits the fan, like a location where the team would regroup and deffend the position in case they got pushed back by deffenders as opposed to initially spawning there with gliders.
