The point I am trying to make here is that while hard-cancel signal travels necessarily out-of-band, the graceful shutdown signal must be, equally necessarily, passed in-band.
Minor, but in band vs out of band isn’t really a firm distinction. Like, there’s a sense in which SIGINT is in band and SIGKILL is out of band, but I think that most of the time, that’s not the natural way to think of it.
