Are you being serious? I agree that there can be "some kind of ancillary function that is non-essential" but in the case of failed logging you should try sending an email / showing some warning if you have a GUI / try other outputs / crash with a meaningful error especially if you are running under some sort of supervisor... etc.

Of course that doesn't invalidate your main point.
