Yeah, it's a bad idea. On the dev app server the keys will increase nicely like that, but in production there's no guarantee that will happen. In fact, I'm pretty sure it's guaranteed that they won't increase nicely.
I wrote a test the other day where I was creating models in a loop and the key_ids were all over the place.
