> In my experience there's no impact.  Even if a group of MOTU get fired up and fix a bunch of stuff, getting things reviewed isn't an issue.   Some releases we do get a motivated group at the end that really makes a good bunch of changes. It's amazing what a few focused MOTU can accomplish.

There is an impact to those members of the release team who are also
working on stabilizing the final images in terms of dealing with the
interrupts and context switches.  The last week is pretty full with
getting the last fixes in and tested, updating release notes, announces,
etc.   Since the archive is frozen,  every fix still does need to be
reviewed for sanity before being accepted. 

That being said,  if the release team members who are not directly
working on the final images (usually those without archive admin
capability) are willing to be the handle the bulk reviews and
interfacing in #ubuntu-motu channel during this period it could be
workable to have the later date.   There does need to be a 'go to'
contact on the release team identified, so folks know who to ping during
the interval if they want something reviewed/included for the unseeded
universe packages.  

Stefano Rivera (tumbleweed) has been the MOTU representative this cycle,
so he seems to be the logical "go to" person.  Note, this does not mean
that he has to do all the reviews.  :)   Basically he's there to be
contacted when someone may not have an existing relationship with
another release team member to ask, and help balance the review load. 
I've checked with him and he's willing to help out over the next couple
of weeks in this way.   

If after the release meeting, there are no objections brought up.   I'll
do the updates to the existing process pages this afternoon to reflect
the new timeline, create a new one for Unseeded Universe Freeze along
the line of what is outlined above, and send out mail to the developers.
