For what use case? We do use `rsync` instead of `cp` in some capacity, even for local-to-local file copy - as there is slightly more verification of a successful copy, and the destination is a quirky flash medium. Not sure how SCP would help here.
I mean that my train of though was first "scp, it seems, can do everything cp can, and more, so let's drop cp and use scp instead", then "but hey, rsync, it seems, can do everything that scp can, and more, so let's drop scp too and use rsync instead".
Possibly. `cp` is ancient and rather basic; OTOH, it is everywhere (as opposed to `rsync`, which I found out the hard way) and it is tiny (fewer toggles to push - less stuff to break).
