His rationale was that removing these standardness restrictions could potentially open up additional transaction pinning(1) vectors. Since this is a potential problem with any relaxation of standardness rules, I don't consider this to be an important concern. But consider this email your notice. At least some miners appear to be mining non-bitcoin-core-standard transactions. So with respect to the hash power of those miners these pinning vectors may in fact exist already. # References 1) https://bitcoinops.org/en/topics/transaction-pinning/ -- https://petertodd.org 'peter'[:-1]@petertodd.org
