I think the best mention was to split up the inventory so that you had
each directory having just its inventory, and then the base inventory
becomes the tree root id.

We need tree root ids to properly support nested branches anyway (both
by-value and by-reference work better with a root id).

Right now, you could find it because you have other meta-information
(you have the working inventory). But you are completely correct. Each
revision would need to add a 'tree-root-id' parameter, so that we can
look up in remote.

+1 to the concept.
