There are some useful cases where silent overwriting is not desired: for example in unit testing, when you use multiple fixture files, and can duplicate PK by mistake. It has another advantage - django won't be checking if instance already exists in database, so test fixtures will load a bit faster.
This issue is not only connected with unit testing, I just give you practical example.
