Here I am proposing to change the `requests_hash` commitment so that empty items are excluded. The point of this is to ensure a stable empty requests hash which is independent of fork. Having such a hash makes testing a lot easier, and it mirrors how other execution-layer commitments behave.

Ok, this works, but this assumes that request_type is one byte, which is not specified.
I would also somewhere note that this thus checks that there is any request_data (without request_data then r len is indeed 1 (assuming that it is a Bytes1 type)). I initially thought this was off and should be len(r) >= 1.

The type will always be one byte. We should probably add that to the EIP.
To me this is already a good reason for the change! :) |

The `requestType` of empty lists is no longer part of the requests hash. - ethereum/EIPs#8989
