Personally I would advocate for a static layout here. Can we accomplish the stated goal with IDs? Something like:
genesis_hash: [u8; 32] // (Hash)
blockchain: [u8; 8]
cluster: [u8; 8]
I guess that introduces the problem of where to "register" chain IDs, but I think we were going to have that problem anyway, right?

I think it'd be nice to have the cluster identifier be typed but that could easily be accomplished with helpers in the SDK.
I think the static type makes sense. The chain ID is really for continuity for Devnet resets and debugging so relying on an external registry also works!
