I agree... but what is it? :)

Sure, one lesson is "trust is tricky". Perhaps another is "get your
trust as close to the source as possible", although that's doesn't
always help.

I am wondering if we can also take something here to the reoccurring
debate about the utility of regular KSK rollovers.

In that debate, one argument is that since there is no cryptological
motivation for a KSK rollover, that these should be done only when the
KSK is possibly compromised. The other argument is that we need to do
regular rollovers so that when an emergency rollover is necessary it
will work.

This strikes me as indicating that even with regular rollovers, things
will still break. Which kind of supports the idea of rolling over only
in emergency, doesn't it? At least in that case you *might* never have
to go through the pain of making some domains go dark for some users....
