We take it as it comes.

Currently, it's perfectly possible to accept zeroconf transactions with
only a very small chance of double spend. As long as it's only possible to
double spend a small fraction of the time, it's an acceptable cost to us in
exchange for being able to provide a fast checkout experience to customers
and merchants.

If the status quo changes, then we will need to investigate alternatives
(which realistically would include mining contracts, or only accepting
instant payments from other trusted hosted wallets, which would be a net
loss for decentralization).

Long term we would prefer to see an open, decentralized solution, such as
payment channels / green addresses / lightening networks. However, I think
as a community we are a long way away from choosing a standard here and
implementing it across all popular wallet software and merchant processors.
