Plain text is way harder than people think. Partly because the reflow rules change depending if you are making edits in front of or behind the cursor/point of action.

On anything structured that doesn't require re-flow this approach makes some sense.

Lists, Grids, etc, there are pro/cons but it makes sense.

In this case you ARE causing reflow, so content and format change at the same time.

With normal cut and paste the reflow happens at the point of attention, and the final state paste keeps your eye right at the point of action.

This jumping around stuff means you are doubley losing tracking if you paste below the cut point. This is effectively an out of bound focus shift. This has higher cognitive penalty because layout is no longer occurring in serial but in parallel in multiple places.

idempotence, types, rejection of global state, all of these "engineering" rules go out the window when you enter the realm of mereological nihilism that is text editing.

The best you can do it think of things as causal chains like some CRDTs do.
