Most of the tests shows that bzip2 is slower to decompress an archive and
has a smaller gain than LZMA.

AFAIK, allowing LZMA in DAK is just a matter of changing one line in
DAK.
Do you have more details about LZMA being deprecated and replaced by XZ?
If we want to allow XZ, it will be for squeeze + 1 only.
BTW, I think we should also to disallow the compression for some
Debian packages. There is no point of compressing a package with gzip
when it contains a single source.bz2 (or .gz or .lzma) and a
changelog.gz. This is already supported by the tools, but not by DAK.
