Can you actually? If some layer of that storage stack stops working then you can no longer access your existing data, because all these layers need to work correctly to correctly reassemble the data read from disk.

It's a hypothetical scenario :) In reality if there's a project shutdown there would be enough time to migrate to a different setup. Of course it would be annoying to do, but at least it's possible. With a system like ZFS I'm risking having to change the filesystem, volume manager, storage array, encryption and whatever other feature I depended on. It's a lot to buy into.
