That's a very liberal way to define "confirmation", especially since modern OSes will delete trashed items on a rolling 30-day basis, without any further action.

To rephrase:

> mv dir .old-dir && rm -r .old-dir &

it's how most GUI desktops “delete” stuff, they just run the two actions separately

It's kind of a stretch anyway since the core idea of the command was the final `&`
