+1 for 2. :-)

Implementing reverse traversal for what's essentially an arbitrary order is
meaningless at best, and gives a false sense of a non-existent fixed ordering.

I think retaining insertion order is a needless overhead; if you needed such a
thing, it should be implemented in the library instead.
