🍓 Suggested change

Much like the warning given when environments will have access to the internet - it would be useful to have a prompt explicitly stating the name of the environment that is being torn down

🚂 How could this be done?

Add the name to the console print around here

Should be easy to add. Is this useful feedback for users? You would have typed the name shortly before in the command.

Yes the command is dsh sre teardown name
So it is there on the screen, but for such a destructive process I'd personally appreciate another confirmation
