The usual reasons to choose this pattern are "because versioning" and "location transparency". When the resources you interact with are local OR you have tight over the environment, you're totally right, there's little reason to introduce "middle procs". When there's a risk that different versions of things will manipulate resources in incompatible ways then the rpc layer makes sense.

The resources are local in this case - it specifically uses a Unix domain socket. And if/when the "different versions of things" are an issue, they can just as well affect the RPC layer.

  OK yeah, fair point, sorry, I didn't evaluate the context sufficiently.
