The way we do here is that we have a snapshot repository that store the 
snapshot (forest extension -> fsnap) of the whole tree at a certain 
moment in time. Those snapshot are enough to restore the whole tree in 
the state of the release. Those state can be uniquely identified with 
the revision id of the snapshot repository.

We did not figured out yet how subrepo could help us removing our 
dependency on the deprecated forest extension. But we'd be happy to see 
if someone has similar experience though.
