I think for the archive, this is of limited value.  We need to be clear about practices that 
are appropriate for the archive and ones that are appropriate for 3rd party repositories such 
as PPAs.

One thing I've wanted is a different release target for PPA uploads.  If the upload target for 
PPA uploads was something like intrepid-ppa, then I' feel more comfortable 
with automation around multiple releases.  Maybe "debuild -S -ppa-all"?
