No, in script mode parted defaults to the safe option. Automatically
saying yes will lead to data loss so it defaults to know. I admit the
message is misleading, this is because of how parted handles warnings
like this and it could use some improvement.
I don't really have any suggestion for working around this other than
doing it in interactive mode.

No, it's there for the tests. But there's no plan to remove it since the
tests depend on it. But I really don't recommend automating things that
could lose data.
