The BIP146 has been updated to include NULLDUMMY* as part of the softfork:
https://github.com/bitcoin/bips/pull/435
NULLDUMMY is a trivial softfork to fix malleability related to the extra stack element consumed by CHECKMULTISIG(VERIFY). It is probably more important than LOW_S since without that an attacker may replace the stack element with any value.
