To necromance this old thread, I wanted to give a heads up that we're about to get a
cool feature in Bodhi in response to this thread:
With that pull request, there will be a new request state called "batched". When
non-priority updates reach the karma threshold, they will go into request:batched
instead of request:stable (they will remain status:testing). Once a week, a cron script
will look for all updates in the batched state and will switch them all the
request:stable. Then they will continue on as they do today. This should help us to reduce
the daily churn of Fedora updates for end-users to only be updates they truly need. It may
also make the masher be a little faster on 6 days of the week (and slower on one ☺).
There will still be a little more polish work to do after that pull request is merged. For
example, for non-autokarma updates we want to change the "push to stable" button
to be "push to batched".
 The code considers two things to determine whether the update is priority or not:
security updates are high prioritity, and urgent updates are considered high priority. All
other updates are considered "normal" and will go through the new batched
