Well, the "No one should be affected" is not entirely true. I'm
packaging <super cool game>, use copr to build it, advertise it. My
account is compromised, I don't realize it. Attacker uses the token to
build <super cool game + my own little backdoor>, all the users of the
repo get the update and "my own little backdoor" with it :)
You're gonna say it isn't much different from the current situation w/
the koji certificate.

So yes, it is problaby not much different. It's just that 1 year seems a
lot to me but maybe it's just me :)
The list of IP address used w/ an account can be nice, but as soon as
you start using "public" access point (you build a package in a train,
airport, train station...) then there is a new IP which you probably
won't be able to tell 2 months later if it was you or not. So that might
not help here.
