No need for additional_flags here.

You've got to wait for the prompt explicitly.  If you ever leave expect
in a state where two prompts should be arriving, it won't know which
is which; if it sees them separately, you can get out of sync and all
tests will fail with unknown output.  That's one advantage of using
runto_main followed by an explicit continue.

Looks otherwise OK to me.
