At least on Linux, PID1's death is an instant kernel panic. As such, it's wise to keep any service management logic out of it. If the svscan process dies, then your system is still chugging along and you can intervene to restore the supervision tree (otherwise svscan inspects supervise processes at a regular 5s interval). If you have some really critical process, then you could integrate a checkpointer into the run script chain so that you can just pick off from the last image of the process state with minimal interruption.
