Ah yes, very good point. Anything with a subtree merge would have several
roots, for example.

I suppose the thing that makes root commits special is their lack of
parents, so the most direct way to get a list of root commits for the
current branch would just be

  git rev-list --max-parents=0 HEAD

making the recipe

  ROOT=$(git rev-list --max-parents=0 master)
  git checkout "$ROOT" -- # will fail if more than one root
  git commit --amend
  git rebase [--interactive] --onto HEAD "$ROOT" master

Okay, I'll take a look when I finish my current project!

Best wishes,
