> I've seen many engineers ignoring these because it's "an edge case", to realize later they have a massive data integrity problem. Massive optimism detected at the part of "to realize later". Also, if you have "edge case" with high (close to 1 but lower than 1) probability of successful outcome, with more and more tries probability of all outcomes being successful moves to zero (multiplication of lower than 1 values) and probability of at least single failed outcome goes to 1 (addition of lower than 1 values). You still have to handle low probability edge cases.
