So I'm unclear on what we're trying to optimize when a tpclear nukes less than the corresponding tptraverse visits. I suppose "code space" is one decent answer to that.

In the case of type objects, it's not a matter of optimization but of correctness. If you were clearing all slots of a type object, you'd lose state that is still needed later on; see the comment for typeobject.c:2.150.
