How do we know whether the old CA or the new CA is the secure one?  This
email "from Dennis" could easily be a spoof or a phish:

First give us your username and password.  We promise not to abuse it
unduly.

Then overwrite the securely signed key that has validated the
real web site for years -- with whatever we send you from our spoof site.

Then you'll REALLY be secure.

I'm serious.  Whether or not there's been a security compromise on
the Fedora servers, it would be easy for the people who did it to pull
a DNS spoof, get a bunch more passwords, and get many community members
to believe that the spoof site is the real thing.

I only recommend replacing your Fedora certificate if you have been
asked to do so personally, e.g. by phone from a voice that you
recognize as a friend or colleague in Fedora.
