Rust made the same call. Panic isn't supposed to be "I'm not sure what to do now, maybe my caller will know?". That is an error not a panic amd you return it. A panic is for "I just realized I or someone else did something really bad and the invariants of everything are now in question, hit the breakers, lets try this again". If your dependency library, like so many, panicked rather than take the time and effort to check the conditions that would cause an out of bounds access, then they are bad and they should feel bad, fork and merge the fix and don't say anything, they will feel the shame.
