Consider adding "discard-changes": true

[joelpittet]

By adding this:

"config": {
    "discard-changes": true
}

You can have your build tools use -n flag without leaving dirty changes around.

I can't think of a situation where you'd like to keep this as the default false so I'm proposing it be added to this.

Ah yes, I think now I understand. "discard-changes": true will only be taken into account when running the command with the --no-interaction option (or -n flag). That makes sense.

This was added in 2020 when 9.x was created.
