Wouldn't be that sure about that. Getting the wrong answer can be a serious security problem. Not completing the operation... well, it is not good, but that's it.
Keep in mind that in a kernel panic no hardware is assumed to work, so assumptions like "just write to storage!" isn't an assumption you can make, you're in a panic the IO could have been literally pulled out.
So just change that assumption since for these edge cases that is an incorrect assumption.
