I think describing these as "small" changes is misleading; the chance of
regression from completely changing the rendering backend for CUPS is quite
high.  While the impact of the bug is significant and therefore it's worth
considering for an SRU, the change needs to be uploaded first to karmic and
tested there, and we ought to have some aggressive regression testing for
this change within jaunty-proposed prior to publishing the SRU.
