There's been a discussion on the dev-list about this change -- even though the
interface was documented in 1.32 it wasn't enforced.  Frankly, I don't think
it has hit everyone (Robert included) how intrusive this change is. There's a
couple of us (me included) that think this change is a really bad idea, but we
haven't convinced Robert.  Anyway, Robert's view is that this will help
prevent downstream errors related to object tracking.
