API - Threat Situatuation

Blizz has brought in the functions about the threat in patch 3.x.
Yeah its true, that you can math the threat out, but its just calculated and i think, its group/raid general, not mob-based calculated in KTM.
My idea now:
Is there any possible way to enhance the blizz api without client-patches?
I think on the way of an internal channel like addons do.
API - UnitDetailedThreatSituation (reference)
btw: there is a spoiler tag missing.
