Comment 8 for bug 143998

The only reasons I know of are:

1- There may be some hardcore users, who wish to keep using baz even though it is orphaned by upstream. (Robert pointed (indirectly) to http://lists-archives.org/debian-devel/124715-bug-433143-itp-bzr-rebase-rebase-plugin-for-bazaar.html)

2- baz is needed to upgrade old archives to bzr using bzrtools, and very likely to upgrade them using other tools like tailor. So even if no one is still using baz, there may be people who will someday need it to retrieve historical data.

I'm happy to leave it up to the people doing the work whether these are a strong enough reason to keep baz around in a package named "baz". It has seemed to me like Debian has tended to package everything that might be useful to somewhere that's technically and legally possible.
