Extrapolating from our experience from two-week deploy cycles and what bugs we find at each stage, would moving to a one-week deploy cycle substantially increase the number of users exposed to really bad bugs?
For instance, if we're currently finding and fixing about 2 deployment blocker bugs per cycle after the mediawiki.org deploy but before the non-Wikipedias deploy, that data might imply that we should structure a 1-week cycle differently -- perhaps with three stages rather than two.
I don't know what the stats are, but my intuition is that it's not generally that high. However, the ones we find are kinda big, so it still makes me nervous to go that route.
I've edited the page, called Greg's proposal "Alternative A", and added "Alternative B" which provides a little bit of time for catching issues on mw.org:
