A big asteroid could hit the earth
I think your question falls in the realm of worrying a bit too much. However, if I had to venture anything, I think USCIS runs some quality control programs, perhaps your application could fall under quality control scrutiny and if it is found that something was overlooked during interview or processing it could lead to "revoking" the oath letter. This is pure speculation, as I have never heard of such case, however your question was purely speculative, so it is fit that the answer is speculative too
My 2 cents.
