Can PLIC ensure that the ID read by targets other than the first is 0 #14

I found that sometimes the value read by two targets from the ID register is not 0. I think we should ensure that only the first target reads non-0 from the ID register, and the rest should read 0. Is there any reason PLIC behave like this? image
