> With OAK-2673, it's now possible to have hidden intermediate nodes created concurrently.
> So, a scenario like:
> {noformat}
> start -> /:hidden
> N1 creates /:hiddent/parent/node1
> N2 creates /:hidden/parent/node2
> {noformat}
> is allowed.
> But, if N2's creation of {{parent}} got persisted later than that on N1, then N2 is currently able to delete {{parent}} even though there's {{node1}}.
