I've had informal discussions about this - there's enough interest IMO to open a KEP & I will present this issue at upcoming sig-node, sig-storage mtgs with a KEP draft

Can you use the Volume Populator? It allows you to create a PVC from an extenal data source. https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/1495-volume-populators
