Let me start by saying that I concur with you completely.
I think that some have asked why we are rolling at all, in order to more
precisely understand what threats we are mitigating.

I think that may be situations which pre-publication of standby keys might not
mitigate.  I think that we won't be sure until we write down the reasons for
an emergency key-roll.  As a small detail; who would make that call, and how
much time would they have to make the decision?
