This seems to be more of a problem with centralized mining than zeroconf
transactions.

We have no contracts in place or plans to do this that I am aware of.

However, we do rely pretty heavily on zeroconf transactions for merchant
processing, so if any significant portion of the mining pools started
running your unsafe RBF patch, then we would probably need to look into
this as a way to prevent fraud.

In the long term, I would love to see a safe, decentralized solution for
accepting zeroconf transactions. However, right now there is no such
solution supported by any wallets in use, and I don't think breaking the
current bitcoin behavior for everyone is the best way to achieve this.
