Some feedback on the presets. On Nim side it's very easy to use them at compile-time. We pass a compile-time switch to the compiler to tell it to import one preset or the other: status-im/nim-beacon-chain#269.
We are passing the shuffling official shuffling minimal and mainnet shuffling tests for example
We've finished adoption of latest github tests harmony-dev/beacon-chain-java#144 . There are still two cases which we ignore, but first is definitely minor, the other one is more about infrastructure and isn't associated with particular test case, so I could say we are passing all tests from https://github.com/ethereum/eth2.0-spec-tests now.
I've found several issues with our spec implementation during adoption of tests, so the core goal of any tests is reached here! Thanks @protolambda for a big amount of work in tests development and building skeletons/core classes to simplify tests development.
