I don't think it is. The only reference I can find is

and there it's set to 32767.
0 is
[SI_USER](https://github.com/torvalds/linux/blob/94305e83eccb3120c921cd3a015cd74731140bac/include/uapi/asm-generic/siginfo.h#L174),
which is used by `kill`, so in theory uid/pid should be set. However, it's
also used as a default value, so maybe not printing the uid/pid in this case is
actually correct:
