Risker,
we've consistently communicated that we'll iteratively update the Pending Changes codebase with fixes to address known issues, as documented on:
http://www.mediawiki.org/wiki/Pending_Changes_enwiki_trial/Roadmap#November_...
This is the assumption on which hundreds of people voted in the enwiki poll that just took place, where this date was explicitly referenced. We're going to do our best to meet that deployment date.
How and under what conditions Pending Changes is used is up to the enwiki community. All we're doing is leaving the feature in place: the community can decide to defer its continued usage, to narrow it, to broaden it, to restrict it in the scope of a trial, or to discontinue it. We're going to base our resource allocation for future development as much as possible on the emerging consensus in the enwiki community, and we'll try to support that continuing process with data as much as possible. It's evident that these discussions are still very much in flux.
