I like that change, as I typically install cvsnt and then
rm -fv /etc/rc?.d/S??cvsnt.

I think so.

Another option is to create (only if it doesn't exist, and after doing
a version number comparison with dpkg --compare-versions to see if
this is a version where it should be created) /etc/defaults/cvsnt as a
non-conffile configuration file, with the value CVSNTD determined by:
. if it's an initial installation, "no";
. otherwise, detect if cvslockd is running with s-s-d:
postinst:
f=/etc/defaults/cvsnt
v=2.5.03.2382-3.3
[ ! -e "$f" ] && dpkg --compare-versions "$2" le "$v" && {
CVSNTD=no
[ -n "$2" ] && start-stop-daemon --quiet --stop --test -n cvslockd -x /usr/bin/cvslockd && CVSNTD=yes
echo "Creating /etc/defaults/cvsnt with CVSNTD=$CVSNTD" >&2
echo "CVSNTD=$CVSNTD" >"$f"
}
Perhaps you could do something a bit more sophisticated, instead of
doing [ ! -e "$f" ] you could do:
grep '^[[:space:]]*CVSNTD' "$f" >/dev/null || {
dpkg --compare=-versions "$2" le "$v" && {
CVSNTD=no
[ -n "$2" ] && start-stop-daemon --quiet --stop --test -n cvslockd -x /usr/bin/cvslockd && CVSNTD=yes
echo "Initializing /etc/defaults/cvsnt with CVSNTD=$CVSNTD" >&2
echo "CVSNTD=$CVSNTD" >>"$f"
}
}
