    Good news on this: The NetCode and Physics packages are dependent upon the Entities package, so any Entities Transform related changes (like double precision) must be compatible with Netcode out of the box. I.e. If it ships, you can expect it to be supported by both Physics and Netcode, unless explicitly stated otherwise.

    That's not what I am referring to. I was referring to this comment:

    Ah, apologies. As far as I know, we don't have plans around abstracting the LocalTransform into an interface (or DOTS equivalent abstraction). I.e. If you made your own Transforms, you'd likely need to make local modifications to the NetCode package, as it would be hard/impossible for us to generalize. What we can do is document (and talk through) how we use Transforms.

    I don't mind having to write custom systems, but if I have to explicitly modify the NetCode package internals (same for Physics), that's a problem.

    Can you make sure that NetCode and Physics only use one single transform component like final one that stores WorldTransformation/Matrix so any 3rd party transform solution will need only to fill this component to be compatible with other subsystems?
