Ubuntu's britney doesn't get you more than the package builds, installs, and 
doesn't break installability of other packages.  For something that actual 
users are expected to use, that is nowhere near sufficient.

Beta and otherwise buggy software gets uploaded to Debian Unstable all the 
time.  To pretend otherwise is begging for trouble.  There is even less in 
Ubuntu to prevent such packages from getting into the release pocket than 
there is in Debian where time and RC bugs are factored in.
