Summary:
Ref T13164. See PHI774. Fixes T12435.
Since Phriction is hierarchical, there isn't a super strong motivation to support Spaces: you can generally set policies on a small number of documents to get the desired effective policy behavior.
However, it still improves consistency and there's no reason //not// to support Spaces. In the case where you have some moderately weird/complex policy on one or more Spaces, using Spaces to define the policy behavior can make things a bit simpler and easier to understand.
This probably doesn't actually fix whatever the root problem in T12435 was (complicated, non-hierarchical access policies?). See also a bunch of discussion in T12442. So we might end up going beyond this to address other use cases, but I think this is reasonable regardless.
Test Plan: Created and edited Phriction documents and shifted them between Spaces. Searched by Space, etc.
