I wont go out of my way to shoot a chute, but if it is over a town I need or base I will take it out.  Bailing over your own maproom to camp?  I have seen it.  Why do you think it takes 20 or so troops to take a field?  Think about it.  
As in real life.  I didnt get to ask my Granddad that.  I havent seen it in his diaries and I expect I will not.  I am not sure that it was exaclty condoned or condemed by either side.  It happened I am sure of.
