If you want abstract IDs, they must be abstract, so not representing
hardware registers. Then they start at 1 and are incremented by 1.

Other option is to skip such IDs entirely and use register
offsets/addresses directly, like Arnd suggested in linked documents. I
think he expressed it clearly, so please read his answers which I linked
in previous discussion.

There is no single reason to store register addresses/values/offsets as
binding headers. These are not bindings.

Best regards,
Krzysztof
