Chazza [1] filed a deletion request for compiz-bzr [2]:

Requesting deletion of this package as the slow pace of Compiz development and lengthy review processes make a development package redundant. More often than not, what's provided by this package doesn't differ from the stable version at all. I'm requesting deletion instead of a merger with compiz as a merger would create a mess of a comment history largely made up of duplicated announcements by me.
