That's exactly my point, if we ever got to the point where we could
manage graphs (in general) I don't think you'd need to care about trees
anymore. Internally, software might optimize the management of all
kinds of special cases (not just trees), but if we've got Michaels
non-instance specific network exchange capability then at an interface
level you shouldn't care anymore?
