I would argue for the confidence as well. I understand that you want it to interact with digital signatures, but I know we’re using it already in STIX 1.x. We use the confidence field as Terry described, to give our analysts some hint how much they should care about something if they see it in traffic or how likely we believe it could be to cause false positives. Every single thing in our database has a confidence on it.

I would also push for incident (for our use) and also for internationalization for the sake of increased adoption.

Confidence does not really make sense before we have digital signatures, neither does the opinion object.. Without digital signatures first, there is no "real" confidence or opinion as everything could be faked.
