I'm not horribly opposed to that change, but the reason that I chose to do it this way is that those arguments are very similar and it seemed like it would be very easy to screw up the ordering, which would likely lead to some very odd and confusing behavior that might be hard to troubleshoot.  I prefer it this way because it forces the caller to be explicit.

If you have strong feelings about doing it the other way, it's an easy change, so I can switch it.
