This looks great, thanks a lot for this (will have to test locally). One small point regarding correctness and clarity (for devnet-4).
Side-note, in devnet-5 this will get easier, since the empty request hash will be the empty sha256 hash, see:
(We will nevertheless need this change to import genesis blocks which the requests hash, plus we also need the specific empty hash for devnet-4 :) )

This here would become part of the official API of the libraries and it would be hard "to get rid of it" if things change, so let's please not do this yet as long as specs are still changing and rather hardcode in blockchain.

Hi Holger, good point, I did somewhat notice this but note that the "empty requests hash" will be gone starting of devnet-5 (see: ethereum/EIPs#8989), where it is the empty sha256 hash and not this thing with encoded constants (so we can get rid of this constant!). But I agree it should not have been put in the util constants (note: this PR is not merged into master, it is merged in our devnet4 branch, so for now this is fine! 😄 )

Should nevertheless not forget to remove this constant 😄 👍

These things DO have some tendency to get forgotten, so I would still pledge to just give this a quick update now and we are done with it.

Yes you are right, will do right away 👍

Description
Adds the request hash to the genesis block to enable running tests on hive:
consume engineandconsume rlp.Reproduce Hive Passes
Using the following hive branch spencer-tb@prague-devnet-4-ethjs run either of:
Empty Requests Hash
Note the keccak256 of the empty requests should account for the type prefixing, hence why:
and not the default
