You should know based on the compatible string what the number and order of register ranges are. reg is not something we want evolving over time. > So, can I update the "reg" and add "reg-names" as below to the binding and > depend on reg-names for the ordering of reg?

I'm okay with using this for convenience of the client not having to care which compatible the block is, but the above should still be met. Also, you could add a cell which is the index to the register range you need.
