I think ptrace API never promised that it will be possible to "create new signal" by passing non-zero data - only that the already pending signal can be passed, altered or suppressed. If there *are* cases where "create new signal" currently works, it's a quirk.
I changed doc to reflect this. If we tighten it up so that we can state that all such attempts will be ignored, we can update docs.
