The topic of leaking this type of information has been discussed for probably a few hours worth of meeting time over many meetings. I think many people consider it a pretty big deal. It relates to the whole finger printing browser issue if you are trying to find it.  I realize that it might be hard to understand why without reviewing the minutes from the old meetings. And to be brutally honest, I have complained before that the minutes are so bad I can't figure out what happened at some of the meetings but the minutes are no worse than other WGs.
