The current Bundle traits are data-oriented, exposing properties of the bundle, and fairly complex as a result of that, and somewhat unstable besides. This ugliness is part of why they're currently considered an impl detail. If we instead orient the trait interfaces around performing desired operations directly, the result might be significantly cleaner, even after exposing necessary interfaces on World/etc for implementers to call into.
