Yeah, that's valid, I have removed the check and simplify.
Yeah, I would prefer a default 'send everything' policy when someone loads
the package, as long as it's otherwise configured. That said, it will require
a bit of Metron testing to make sure that it can handle that. We don't
currently handle some of the less interesting logs that are on by default, like
packet filter or loaded scripts.

> Right now, you must specify which logs you want to send to kafka via
> metron-bro-plugin-kafka. This would allow the additional feature of
> excluding certain logs, and sending everything else.
