However, to me the bigger concern is the student that can perform the technique competently on the mat amongst friends, but in a real situation, you just know they could never pull it off.
Absolutely, even in training this comes up. How many people can honestly say that the first time they sparred with hard contact and hits to the face that they where "ok" with it right off the bat? Not turning away, being able to counter punch, push into an attack, hit back with intent?
It's not easy, not even in a sport environement with friends. Actively trying to hurt someone is something a lot of people are not mentally capable of, even when the other person is doing the same and they are wearning safety equipment.
So in sport training there is always the question of how far do you want to take it? Light training, limited contact, heavy on padding? Moderate contact, gloves and open face gear? Heavy contact and heavy gear? Heavy contact and minimal gear (think dog brothers)? Full MMA competitive fighting?
The farther you are willing to go the better you'll get, too far of course can be too dangerous. Every time you step it up you don't
know how you will react, you could start taking hits and freeze, you could be unable to hit with enough intent to do the damage needed to succeed.
But to write sport fighting off because you don't know at each step and just assume that when the time comes you'll be able to do it seems the wrong way. Training realistically is a progression, you shouldn't go full contact with 4 oz gloves your first sparring session, and no gloves / mouthpiece in a non-controlled environment is quite a big step above that.
