The x86 and Arm backend were, but you fixed it here: https://github.com/llvm/llvm-project/pull/156617/files.
@linuxrocks123 #155491 proposes upstreaming a feature from a non-public backend that violates this, which while it looks to have been rejected, suggests that non-public backends may be doing this as well and I don't want to dismiss that they will be impacted.
