Using grafts requires some cautious, especially when it is used to make
some commits unreachable, because git gc can remove unreachable commits.
Also, a repository with grafts cannot be cloned.  So using grafts looks
like more as workaround rather a real solution.

Would it not be better to save the old branch using "@SVN-NUMBER" as
suffix? Thus, those do not need the old branch can easily delete it.
