@lenkan We have a follow up PR (in progress, almost there) that converts these to specific WitnessOperation, GroupOperation etc... (not generics) so should cleanup some of the things from this PR.

@lenkan Hmm, I feel like this will become annoying. We could just use any instead of unknown in these scenarios, or alternatively offer a bunch of type guard functions but that list could grow quite large and hard to maintain. Thoughts?

@iFergal feel free to approve and merge.

@kentbull Going to see if there's a nice way to serialise the exn resources from exchanges().get and infer types based on the route. Because currently embeds are unknown and it's difficult to work with. You need to cast everything, so Signify should at the very least provide those.

@Sotatek-Patrick-Vu Maybe we should mark as draft for a little while
