So I think my earlier comment saying export is overkill might have been
wrong. The handbook page explaining how zfs checksums work has an
example that explicitly uses export:
[20.3.8. Self-Healing] "Data corruption is simulated by writing random
data to the beginning of one of the disks in the mirror. To prevent ZFS
from healing the data as soon as it is detected, the pool is exported
before the corruption and imported again afterwards."
