In some cases you might have the excuse that, well, you did say on the tin not to do this with the unsafe element. For example if I use Bob's "I need exclusive control of GPIOs 2, 3 and 6" and also Kate's "I need exclusive control of GPIOs 1, 2 and 4" unsafe code, then it's my fault, they did both tell me this requirement and they clash.

But in general this is specifically a bug in the unsafe code. The Rustonomican is very clear that it's not the safe code's fault that your unsafe code doesn't work. In the scenarios with conflicting libraries I guess it's the fault of somebody who linked conflicting libraries, but it's definitely never the safe code.
