I think they are helpful in the sense that the s390x maintainers get
CC:-ed on related patches as well, and if I've got Christian right, he's
interested in getting informed here. For Arm related patches, I guess
you should ask the Arm maintainers first. For x86, it does not really
matter, since the maintainers are the same.
