Unfortunately, yes, it is true many of the things will not work any longer in BWH. The tracking should work. Teleportation is also no longer viable or at least no one has found the offsets, for inside instances. World teleportation is still viable. I beleive that no fall damage and teleport to plane should also still work.
I know for a fact that tracking is possible. I have another program which I use for that. It is also possible to track the following...
