I use a similar pattern for edge cases. We work with weird data and often have processes to cleaning it - non essential but useful for optimisation. Sometimes we’ll have an assumption about the structure based on what we’ve seen before but we can’t be sure that will always be the case. So if the following code requires a certain format, we check the assumption, log if not met and then don’t continue with that cleaning step. More often than not we never see the exception on production.
