How would that benefit a flight simulation where you can't call medic. If you're hit that bad where you can no longer fly properly or become completly immobile, would you want to watch your life ebb away on a monitor?
If you mean plink, plink, plink and suddenly you explode red mist, sure.
The moaning. Well, I've seen those combat videos and I don't think you'll enjoy it that much. Surprisingly, most people are very quiet when they know death is coming.
I also listened to a lot of blackboxes and more often than not, the pilots displayed amazing calmness and professionalism even when they knew that was it.
There was one that stuck with me where a pilot said "I love you, mom." just before recording ended.
And all of the above would probably bump age requirement up for DCS 2.0.
