Did you think it combined the file with the built-in list?
I hadn't given much thought to how the built in would or would not be combined with the contents of the root.hints file.
I always took it that BIND would fall back to the compiled in version if nothing else succeeded.
It is. I'm not even sure you misunderstood the XOR, since you wrote that it tries each server in the root hints file until it gets a successful response. That suggests that you understood that the built-in list is used in place of the file if no file is provided.
The idea that a (maliciously) blank root.hints file would prevent BIND from using the compiled in version is new to me.
