Somehow I'm not surprised that someone responded to that commit with a "sky is falling" message. I wish people would be a little slower with the knee-jerk reactions. Cache sync has been turned on in the DA driver for a very long time now (since the first revision, June 27th, 1997) and there have been very few problems with it. By far, most drives out there do something reasonable when they get this command. I think there are plenty of other things in -current that are much more likely to cause support nightmares and bad publicity.
