Chazza  filed a deletion request for compiz-bzr :
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.
