I might do it if the commits in my stack are mostly independent and I want to commute the ones with `TODO` to be later. This might be so that I can

- run checks on the sequence of done commits, without getting wrong/unhelpful results because of the presence of an unfinished commit in the sequence

- put the done commits up for review now

(This is predicated on certain workflows being acceptable / useful for the user, such as modifying existing commits and reordering commits.)

It's also just an example. You can swap in your favorite query into `-r` if you don't have any need for moving `TODO` commits around. Regardless, Git is not easily able to replicate most such invocations.
