The straight arm technique is very accurate, especially if you're a little guy like me, keeps the recoil manageable (remember not everyone is 6'6" with bear paws ). However you're right in that in most situations that probably won't be the best option. Either you just won't have the time bring it up that high or space constraints. For example if your target is 3-5ft away it'd be kind of silly to take it out that far.
