That's sensible too. The nice things with running commands in "git rebase" are:

* It's likely to be the place where you want to run some tests. The
  typical use-case is that you have a patch serie whose last revision
  passes tests, and you want to check that intermediate commits also do.
  At that point, you probably want to rebase against upstream too, to
  make sure you're developping against the latest revision, before
  sening a patch serie or pushing.

* if the "exec" command fails, you're likely to be exactly in the right
  place to fix it: fix the bug, run "git commit --amend", and "git
  rebase --continue".

The nice thing with your approach (as I understand it) is that it doesn't require rewritting history, and may apply to all commits in non-linear history.
