Is BIP 146, which defines using the low S value, still on the docket to be signalled and implemented given that SegWit fixed the txid malleability issue by moving the witness outside the transaction? I’m asking because it can fix the wtxid malleability which now requires re-syncing of transaction data when it is changed from what it was originally relayed.
Also, will the implementation be a soft-fork which would treat this transactions as non-standard but miners can still include them in the block, or will it treat the transactions with high S value as invalid?
