Traversal mode has become cumbersome to maintain. Every single non-trivial feature required extra work to play with Traversal, and usually caused a trail of follow-up issues. And all that for little gain. We are transplanting the interesting properties to the upcoming I-U mode (which is much less trouble-some), and can ditch Traversal mode altogether.
