While every possible subsystem needs an initialization call, all that does is add the actual initialization task to the render graph system. This allows the render graph to be fully configurable, initializing only those subsystems that the graph needs. Scripted initialization is still separated from startup as render graph creation needs various resources (eg, attachments) defined before creating render and compute passes, but all those need to be created before the subsystems can actually start up.
