[Users] Debian-style init scripts considered harmful?

Debian uses start-stop-daemon in the init scripts to, for one thing,
From the man page:
Note: unless --pidfile is specified, start-stop-daemon behaves similar
to killall(1). start-stop-daemon will scan the process table looking
for any processes which match the process name, uid, and/or gid (if
specified). Any matching process will prevent --start from starting the
daemon. All matching processes will be sent the KILL signal if --stop
is specified. For daemons which have long-lived children which need to
live through a --stop you must specify a pidfile.
For example, nfs-kernel-server does not use --pidfile. It looks for nfsd
processes to kill.
Suppose that the Openvz host and one of its guests were running NFS and,
on the host, one were to run /etc/init.d/nfs-kernel-server stop
As I understand it this would have the side-effect of killing off the
nfsd processes on the guest.
If true, this would seem somewhat... harsh?
