Isn't this how bodhi always worked? One week (two weeks for EPEL) and if doesn't
get negative karma, it gets pushed - no matter if it's an enhancement, or a bugfix, or
a security update.
When creating an update from the web panel, you can un-check the "Auto-request stable
based on time?" box to disable this. When doing this from the command-line... hm, I
don't see any field in the template that'd allow to change this. Time to file a
feature request?
