I think the upstream-* branches would be useful for visualizing the
relation between upstream and Debian history, e.g. using gitk, which is
something SVN couldn't provide.

The procedure looks good to me, but I suspect the "Merge branch
'upstream-unstable'" commit may not be that useful in the upstream repo,
so cherry-picking might be better than merging in the last step.
