In theory, you're right. But the actual practise tends to be very
different. Probably, databases aren't the prime usecase for that.

There could be other scenarios, where a service has to do some
preparations for others to work (maybe certain filesystems mounted,
etc). I remember, eg., problems w/ nfs, when one of the dozens servers
isn't up yet, so they needed to be started in specific order. Years
went by since I last touched that, no idea that's still the case.
