This is the main use case at least in my mind. The worst case scenario
is that I've lost an entire server where I was running Jackrabbit, and
now I need to recreate the repository from the latest backup.

This would be a nice addition, and probably not even that hard at
least for some subsets of the backup, but for me this is a secondary
need.

Such a partial restore should in my mind always be incremental, i.e.
you never remove any of the existing content unless there's a UUID or
name conflict. You can handle these using the standard
importSystemView options, or you could simply abort when conflicts are
encountered.
