I agree on the above statement.

But what if i don't want to use every type that is used in header file
i am including. For ex: I don't want to use resource
structure in my code and i need to include bus.h for some
other definition. Then why should i get a compilation warning.

Again, according to above statement from submitchecklist:
shouldn't bus.h include device.h and resource.h, as it is using
these facilities.
