(Coming into this one late) When I first wrote xdg-shell, I maintained that attaching a NULL buffer should be illegal since it has no benefit compared to destroying the surface, but compositors might not reset all data attached to the surface, making a weird exception where clients depend on bugs where state isn't always reset. And the "resetting of all data" might seem like strange behavior to clients.
Has this rationale changed?
