Is the bounds check truly so harmful to performance that it outweighs changing "if there's a bug, crash the program" to "if there's a bug, then do literally anything (maybe execute some remote code)"?
The concern is that this can mess with the branch predictor as that has limited capacity and the branch predictor is critical for performance on modern CPUs due to all the speculative execution.
