Yes.  Grafts are more convenient to test things out (and make the transition optional for other users of the branch).  Filter-branch should then change the commits according to the grafts, but then that will require all downstream users to "pull -f" at best, and, at worst, rewrite all their own (e.g., topic) branches. 

There are 4 regular users, so it's not that big of a deal.  Still, once is enough...
