Supposing that some operations perform a write on the container,
for example while filling or updating,
then if there is any potential overlap of a read and a write,
the gain of protection is that none of the writes can ever interfere
with one of the read operations.

If there is no write after some point, I would say that "normal means
of protection" includes "no protection is necessary after this point".
