How do you edit a NeRF? Let's say I want to change material of an object in the scene, or rotate part of it, or compose several into a new scene, etc. Or animate it. It's not really a good representation of a 3D scene IMO, unless all you care about is novel view synthesis, which is what it was designed to do. Transforming it to a mesh or SDF is cheating, then it's no longer a NeRF and of course the same cons doesn't apply anymore.
