As a use-case:

On my laptop I have stuff like mysql-server and apache installed, as I
need them sometimes to develop and test stuff, but I don't need them
running all the time and started automatically on boot.
With sysv,  I've removed the S?? symlinks in /etc/rc?.d/ (well,
renamed them to K??) and manually start the services via
/etc/init.d/apache2 when I need them.

Cheers,
Michael
