The last bit was what threw me. It seemed that the kernel was changed to do the right thing, but only as a compatability measure that would be dropped because userspace should be changed to start doing it (which seemed crazy).
It seems that the _warning_ is the compatability measure that will be dropped (or perhaps the ability for userspace to do the wrong thing at all?), and the kernel will continue to DTRT.
It's a bit confusing for those of us coming in late in the discussion. :)
