Nintendo won't brick the wii of homebrew owners, that would just cost them money (for repairs of wiis that are under warranty)
There is no harm in leaving it on there1
well, trucha signing it, obviously. Like when you want to swap movesets in brawl, you gotta trucha sign it, or if you want to modify the game in any other way. He's asking if it's possible with that game.
does it use an IOS that does not have a version with the trucha bug? If so, then well, I'm not an expert on this, but I'd say it would be impossible (unless you somehow patch the IOS version it uses)
The difference is - you were too late. Look, I really appreciate your effort, but I don't like the attitude you have about it ("I was about to do that too!!!")
It's not that I don't believe you, I just don't think it really matters.
