Well, I added OVP after killing three of them because of mistakes during testing. The highest risk of the diode dying is when you are stuffing 1.8A into a 445... That is two $5 drivers. But the thing that matters is that you will need to put in new drivers. That means not only unsoldering the diode and replacing it, but unsoldering the battery contacts, possibly the switch too, removing the thermal adhesive etc. etc. It does not only save a small amount of money, but a pretty considerable amount of work, too. It's not really a big design issue (a SOT-323 diode and a 0603 resistor) too.
