Not if we don't keep them for long. One idea is to rotate them
frequently. But this is mostly a statement of intent and might be more about
how we build the backend than about what we force in the client.
My understanding is that the Fedora project does not control how much
network logging Red Hat does on its behalf, so rotating the UUID might
well not bring back the old anonymity.
My concern here is that the UUID would allow implementation of a service
that gives the current IP address for a system, based on a past
timestamp and observed IP address.
