A lot of modern engines DO surge and when they do it is NOT always a reason to remove it
You can hardly say that the amount of FADEC powered engine stalls is significant to the amount say stalls v/s hours in service of older engines. I personally have yet to see a FADEC engine stall, while they certianly have I just have never been in earshot (I am in earshot of easily 1000 TO's and landings a week). The JT9 and CF6-6 and -50 are pretty much the same era engine. When we stall a CF6 it comes off the wing for inspection. I have had JT9's blow fireballs at me at 85% n1 on the fence and it was never a big deal the pratt used to be a tougher engine while the GE produced better econemy.
When newer engines fail it is usually catastropic, high tolerance, low clearance, higher compression and heat. When they go bang it often results in damage. Trips me out thinking of old JT3 powered DC8's landing, I mean every damb time the applied reverse thrust there was at least one engine popping.
