It's always easy to imagine why things won't work, then decide to do nothing. Sometimes just getting your opponent to respond opens new opportunities, while predicting failure such that you don't bother is a guaranteed path to defeat.

Also, just because they kept previous revisions doesn't necessarily make it pointless, because they'd still be using the edit in the training data. And yes, they can probably figure out how to clean that up, but then let's make them do that and see what happens.

edit: Most importantly, shit posting is fun.
