I do remember there's still some source packages / binary packages in Debian using the bzip2 format. If we are going to do that (which looks reasonable, BTW), a serious archive-wide scan should be made in advance to see how great the impact is and we need to deal with each occurrence. Another issue is that the new toolchain (apt/dpkg/...) will not be able to handle old packages using bzip2. Why not make the bzip2 support optional (like a plugin or something similar)?
