I would actually propose the opposite - we should use mapper lookups as
a last resort and prefer hard-coded service names.  Mapper lookups add
latency, and require developers to have OpenBMC specific domain
knowledge to do something that should otherwise be simple and well
documented.  Mapper indirection also prevents the use of dbus
activation, which drastically simplifies service dependencies.

Thanks,
