Just count the number of bug reports. That seems like a more useful metric anyway. If the users aren't complaining who cares.

It's not a consistent metric. You'll get both spikes around new releases and changes that reflect the automated reporting/ease of reporting changes.

Also, since Fedora is primarily an integration project, many users report bugs upstream.

The same problem arises though as you can't track senders - there's no way of knowing how many reports were produced by a single machine.
