I think that actually one large advantage that we can get from
PROVIDES/REQUIRES is that when you shutdown the system, there is
more information to work with so you can take short cuts.

I.e.:  In SysV if I have:

S01service1d
S02service2d
S03service3d

Then, on shutdown it seems to me that there are implied dependencies
and the system would have to stop each service in turn.

Whereas with a PROVIDES/REQUIRES, the system would understand the
actual dependencies and could potentially run most of the shutdown
scripts in parallel, which could be a major win IMO -- keeping in
mind that a lot of the shutting down will be waiting.
