Is the current protocol on update_states good?
https://github.com/GazzolaLab/Blender-Soft-Rod/blob/96190a19332ca64d453ee41bbeaf246decdd8dfc/src/bsr/geometry/protocol.py#L51-L52

Will it be better to change *args to **kwargs? Since the states might be different for different objects?

I have the following protocol on update_material:

Both args and kwargs can support all kinds of state. The difference is whether we want to be called with explicit parameter name or just an order.

I'll probably need to see what kind of parameters are suited for update_material to make the decision. For update_states, I would prefer using args.

If args is used, then the order of arguments matters, right?

For update_material, I think kwargs might be better.

In the following case, if the radii does not need to be updated, it still needs to be provided, right?
