https://pubs.opengroup.org/onlinepubs/9799919799/ seems to indicate that the "default action is to ignore the signal", which is unclear to me. I think it means that the signal will not cause invocation of a user handler or abort the process, but does this also mean that wait and waited won't work?

In any case, I agree with @RogerRiggs that keeping this behavior is fine.
