Since the existing device paths disappear entirely, ZFS should be able
to search for and find the drives and bring the pool online, even if the
device paths have changed.

However, there is risk if ZFS picks the /dev/sdX devices to use going
forward.  Those paths aren't guaranteed to be stable across reboots,
especially when devices are added to or removed from the system.  And
since ZFS doesn't export and re-import the pool across reboots, if
existing drives' device paths shuffle around without an export/import,
that can confuse ZFS and cause pool corruption.

If ZFS picks the /dev/disk/by-id/wwn-* devices to use, as happened in
this example case, those are stable and this isn't a problem, but I've
seen ZFS pick /dev/sdX in other such situations.
