The point of my original post wasn't to start a big to-do.  My point was
just that future organizers should be more careful.

Once school starts in September, other conferences stop.  I had always
assumed that was part of the reason XDC was scheduled the way that it
was scheduled.  There are basically two events from mid-September to
early October to avoid: LPC / kernel summit and Khronos meetings.  At
least as far back as 2008, XDC had always been able to avoid both.
Hopefully that long run will be repeated and improved.
