Good catch, I didn't think to dig in there that deep. Well, they have
been really silent about a fairly major change like that. I would have
expected it mentioned in the changelog and/or some blog post ...

That blog post I remember, but the conclusion there seems to be that
positional timewarp introduces occlusion artifacts and a lot of extra
complexity. I didn't sound like something they are intending to
implement at the time.
