There's no need to wait if you're interested and have the time to work
on this part. The pve-storage part itself can actually be worked on
already, and the cases we have now could be converted.

New cases can be added later. The code I'm working on is an independent
tool which could then be integrated into the storage import/export API
after that API has been introduced.
