If needed, I'll update the PEP to be more clear. The sets.py module had two protocols: __as_immutable__() and __as_temporarily_immutable__ (). The first protocol was the one that was dropped -- it triggered with something like "s1.add(s2)" and it automatically created a frozenset copy of s2. The second protocol is used in contains/remove/discard. Alex Martelli successfully lobbied for its retention.
