Wouldn't it be better to return something like Maxuint64 here

Activation time is required. If a fork is activated at genesis the value 0 is used. If the fork is not scheduled to be activated or its activation time is unknown it should not be in the rpc results.
Fix like this?

~Will probably be mostly supplanted by ethereum#32224, but this should do for now for devnet 3.~ Seems like ethereum#32224 is going to take some more time, so I have completed the implementation of eth_config here. It is quite a bit simpler to implement now that the config hashing was removed. --------- Co-authored-by: MariusVanDerWijden <[email protected]> Co-authored-by: Guillaume Ballet <[email protected]> Co-authored-by: rjl493456442 <[email protected]>
