I am not really in a position to comment on how accurate or otherwise this particular answer is, but in a more general case:

• If an answer is sorta-right, but only in a certain set of circumstances, and doesn't make that quite clear, edit it to make it clear, and maybe prompt the OP to expand their answer if they can. An answer that contains a lot of great research but doesn't quite answer the exact question asked can be improved, and we all have that capability.

• If it addresses doesn't directly address the specific circumstances of the question, but does address a broader case, edit it to make this clear. All it takes is a line at the top of the answer: "I'm not sure about [specifics], but in the general case:".

• If an answer is broadly on the right lines, but makes some generalisations that are wrong, edit it to fix them.

• I hope you get the picture by now.

If you're editing an answer and it's getting into a rollback war, that's another problem entirely that we can handle very easily.

In the case of this particular answer, there's a lot of good information and research here, and in my opinion it is perfectly reasonable to expect a big-budget, AAA game to implement safe handling of ALT-F4, and an answer explaining that the exact behaviour can never be known except by the developers (but it's reasonable to expect that this is how it works) is perfectly valid.

This particular answer seems to me to be 90% on the money, and needs a little coaxing to make it perfect.
