That would be nice. Can Broxygen already extract that information?

That argument usually applies to the event engine. For scripts,
considering policy is hard to avoid (and as you say, by default, Bro
1.x did turn everything into an alarm).

Or we could provide an option "default_alarm" or so that enable
ACTION_ALARM as the default, and then put that option into local.bro
for everybody to tune. The question would then be what to default to.
I'm leaning towards alarming by default, in the spirit of showing off
what Bro can do (and showing that *is* doing something).
