There is no statement of how to report issues that can't easily be fixed, etc., just a date certain for the switchover. As to "exceedingly small", are you measuring percentages? Absolute numbers? How many contributors and reviewers is the IESG prepared to lose if they can't get announcements with a reasonable amount of effort? A few hundred (a small number relative to the size of the IETF-Announce distribution)? A few dozen (an "exceedingly small" number on the same scale)?

Again, the announcement didn't imply an experiment to me, only a "here it comes, get ready or be prepared to lose" declaration. > On 1/9/14 12:59 PM, SM wrote: >> My guess about the problem is that people choose "Reply to >> All".

It also creates the impression that the IESG Secretary is responsible for the announcement and that messages questioning the contents of the announcement should be sent to that address. No accidents involved. As you may know, I made that assumption after a perceived problem some days ago and, assuming that "IESG Secretary" was actually a human (she certainly was the last time I talked with her), even copied the "action" address, thereby generating two tickets. So putting that particular address there is clearly a bad idea. But that conclusion justifies the new "noreply" address and an ingress filter at ietf.org which discards any mail sent to that address, not the rest of the changes. > Again, if the experiment flops, we'll re-group.
