Dear, i get your point.....i also understand that IAF jets were in our airspace for a very short time....my point is that the fact that they crossed into our territory and bombing would have been a good reason for us to after them and down them, even if their debris would have fallen inside IOJK.
The example which you have quoted from 2008....that is a case of locking on enemy jets while remaining in own airspace..that is something normal which happens today as well....however, in 2019 case, IAF actually crossed into our airspace....which is entirely different....bombing or no bombing....but their crossing into our airspace is good enough reason for anyone to shoot them down...
