Getting a Canister's Controller On-Chain

Personally, I don’t think that reading the cycle’s balance of a canister is too much information. However, maybe it would be best to leave that up to the community as a whole? Additionally, how can we move this forward? It would be great to get this in-front of a wider portion of the community to get an answer to if we can just make ‘canister_status’ a public method, or if adding a separate method that only returns the list of controllers is the better route.
