Conversation
Adding coinbase_witness to the Sv2NewTemplate message so that it is automatically propagated to other roles in the Stratum v2 ecosystem, rather than assumed to be 0x00...00. This ensures that if this value ever gets consensus meaning, miners only need to upgrade their node software, not the rest of the mining stack. This is a breaking change requiring an updated Stratum v2 spec as well as support on the SRI side.
