It's dangerous because if you are using MySQL for example (it truncates string values), it's very easy for this truncation to happen when not intended, causing data loss that you might not even notice for some time.
If an exception happens when the data is oversized, you will notice it immediately. And there's a classic rule that says the earlier you detect a problem, the easier and less expensive it is to fix.
