Consider Backend federation

[JacobHayes]

Support for federated Backends (Backend that wraps other Backends) might be useful. This would largely be for hierarchical/enterprise situations, eg your team has an existing Backend (with a set of Graphs) while another team has their own Backend. Then, one may "mount" those backends to stitch them into a larger collection exposed via a "federated" Backend to represent the organization/company as a whole.
