I don't have particularly strong feelings on this particular issue, but I do take issue with worrying about edge cases. By definition, edge cases are infrequent and unlikely occurrences. Trying to account for every possibility is a way of making sure nothing ever changes. It's a form of perfect being the enemy of good.
