The signatures of forwardlist::remove and list::remove defined in 22.214.171.124 [forwardlist.ops] before 11 + 126.96.36.199 [list.ops] before 15:
requires EqualityComparable<T> void remove(const T& value);
are asymmetric to their predicate variants (which only require Predicate, not EquivalenceRelation) and with the free algorithm remove (which only require HasEqualTo). Also, nothing in the pre-concept WP N2723 implies that EqualityComparable should be the intended requirement.
[ Batavia (2009-05): ]
We agree with the proposed resolution, but would like additional input from concepts experts.
Move to Review.

Current rationale and wording for this issue is built around concepts. I suggest the issue reverts to Open status. I believe there is enough of an issue to review after concepts are removed from the WP to re-examine the issue in Santa Cruz, rather than resolve as NAD Concepts.
[ 2009-10-10 Daniel adds: ]
Recommend NAD: The concept-free wording as of N2960 has no longer the over-specified requirement EqualityComparable for the remove function that uses ==. In fact, now the same test conditions exists as for the free algorithm remove (23.6.8 [alg.remove]). The error was introduced in the process of conceptifying.
[ 2009-10 Santa Cruz: ]
NAD, solved by the removal of concepts.
Replace in 188.8.131.52 [forwardlist.ops] before 11 and in 184.108.40.206 [list.ops] before 15
EqualityComparable<T>void remove(const T& value);
