Wouldn't really help anyway, even if it worked, because the hypothetical situation is that the user removed that addon following a crash.
Remove the addon, and you'd also be removing the code which would be checking for said flag anyway. So there isn't really a point, heh, and if you aren't removing the addon it'll just resume proper functionality the next time you start the game.

btw, probably a stupid question: X-ing out of the game improperly exits the game and doesn't save saved variables, right? I can imagine a lot of less knowledgeable players doing just that in the same way that people remove usb devices without doing the whole "remove safely" thing first.
