Reboot time matters in telco and control applications. Watchdog timer fails and reboots OS uncleanly. That eats into the 5 minutes of outage per annum implied by 99.999% availability.

Of more value to the typical distribution is the listing of dependencies in the init script. No more guessing at init seqeunce numbers.

Note that parallel starting of daemons can also make the machine boot slower (eg, if daemons fight over disk access). So dependencies need to be a bit more refined than suggested by the article).
