Thanks Ryan, nice, looks good!

If you want to directly continue you can also remove the sharding and casper paramters for the HF files. 😁 These are a bit on the same level, modeled from another perspective with the outlook of an integrated sharding/casper/everything-in-one-place chain (I would say that we can/should remove sharding here as well, there might be some potential need for this in the future, but this is rather hypothetical and who know if this would fit into this structure. Likely rather not.)
