Move en.wikipedia.org to en-dev.wikipedia.org and put only the contents of the Wikipedia 0.5 DVD at en.wikipedia.org.
Betcha we'll suddenly have amazingly efficient procedures for getting good content across from dev to stable.
This also avoids the issue of appearing to declare the Wikipedia project a failure by effectively shutting it down and/or deleting large swathes of it. Since, after all, the impetus for this is nothing but public relations.
