This is not all inclusive, but these things come to mind:

Pro's of 1.5 days vs 5 days:

* Less 0-day SRU's (any bugs found late can be fixed in release, easing
the burden of the heavy SRU process)


* Approving packages means more duties for the release team close to
the release date

* Time spent fixing things in universe is less time spent testing main

I think having more fixes in the released universe is a good thing for
quality, but I worry about the impact, even if its small, on the release
process as a whole.
