It’d depend how wed you are to exactly what you describe there. Swiften’s API would make more sense to do message->setSadexType(…) and message->setSadexData(), and a callback wouldn’t make much sense, you’d just message->getSadexType and message->getSadexData() (or maybe message->getSadex()->(get|set)(Data|Type)(). Not what you describe, but still equivalent to how subject/body work in the API, and I don’t see a problem with adding it.
