Surely, it should be obvious that given the right combination of elements in a crash that an integrated stem would be worse for your crowns than a regular one.
But what advantages do dual crown forks have? Stiffness I'm sure. But don't they increase the chance of damaging your frame? Yep. But we all still run them (well most of us anyway). There is no way a direct mount stem is going to be better for your forks in a crash - that should be obvious to most people. Are they outright more likely to damage your fork? Probably. If you're concerned about that, don't run one. If it's a risk you're willing to accept given the benefits of the integrated designs, then go for it.
But I've got to ask - why focus on the integrated stem issue? There's plenty of components on our bikes where we choose light weight over durability, or function over durability. In fact, if you can't sleep at night over the risk of damaging your crowns, maybe you should reconsider riding a bike down hills and dodging trees as fast as you can.
