The Convenience of Sub-Centivalism in Quantum Physics

The idea of sub-centivalism spaces a thing all by itself versus relationalism spaces is not clear to me. I think that in my view, space should be thought of as a convenient way to talk about relationships between different subsystems in the quantum mechanical wave function. In that sense, I am closer to being a relationalist than a sub- centivalist. For everyday physics, you know, predicting gravitational wave signatures from LIGO, sub-Centivalism might be the way to go.
