Why is `std::flat_set` not yet implemented while `std::flat_map` is already done in libc++20?

cppref shows that std::flat_set is not yet implemented while std::flat_map is already done in libc++20.

And, this proposal shows std::flat_set and std::flat_map are both done in libc++ by Arthur O'Dwyer.

I think std::flat_map and std::flat_set are rather like, and std::flat_map should be more complicated than std::flat_set.

Why is std::flat_map already done while std::flat_set is not yet?
