Ideally the protocol itself stays very minimal and extendable, but integrations and interesting clients should definitely do the kind of stuff you're talking about. and if any of these schemes can be profitable for someone, we might see people picking them up; hell maybe even spec them out and get one crowdfunded, with some kind of "equity-like" limited kickback to the early funders.
