Finally I am not sure if you are aware of bitcoin-s? It's a Bitcoin implementation and toolkit written in pure Scala. Note that it's not yet migrated to Scala 3 from what I can see. But maybe have better luck finding the person you are looking for in their community channels.

how "radically decentralized" the development of the Ethereum core is. In the past half a decade only 133 devs have contributed to Ethereum source code. 2 devs have written 25% of the code. The first 10 developers have written 70% of the Ethereum code. Consensus specifications the ones that all the clients implement. Half are Consensys employees https://github.com/ethereum/consensus-specs

There are over 7000 pending validators on the Ethereum test net. Looks like a lot of people want to practice staking before the Shanghai hardfork

Clients dependent on Consensys core and ETH management repo. A client is just the implementation directed by Consensys written in a different language. Fact is about 10 developers are the only reason those clients will update with staking. https://github.com/ethereum/consensus-specs

For that, we have to take the vanilla deposit contract from the consensus specs: deposit_contract.sol, get the Solidity compiler version 0.6.11, compile the binary of the runtime part, and create an empty deposit tree.
