depends on what our plans for cross-cluster shared storages are ;) but 
yeah, can be left out for now - this is still experimental anyway (also 
added a marker for that for the next revision), so if we re-introduce it 
it's a fairly small breaking change anyway, or we could default to on so 
that only those rare setups with actually shared storages opt out.
